Benefits of Stretch Wrap

Stretch wrap is a packaging and manufacturing material which is used to pack, wrap and secure different items. These wraps find widespread usage in industries where there is a constant need of storing, transporting and shipping large consignments. Besides protecting the goods from getting damaged, stretch wraps provide security from external pollutants. This helps in transporting the goods to their destination, intact.

Stretch wraps are quickly and easily applied by pulling them around a load or pallet of goods. The plastic’s ability to stretch due to the elastic band effect is what holds the load together securely and tightly.

There are two main types of stretch wrap, differentiated by the method of manufacture. These are the Cast stretch wrap and the Blown stretch wrap. Cast film is mainly used in machine or automated applications, while Blown film is used in manual hand-held situations.

Stretch wraps offer many benefits for the user. Besides storing and securing items tightly, stretch wraps provide the following benefits:

Superior protection: a stretch wrapper provides far superior protection than other packaging options. The damages to the products while being shipped are minimised. The wrapper protects the goods from the harmful UV rays and from dirt, dust and moisture. The loads are concealed in opaque films providing better immunity from being pilfered.

Cost effective: stretch wrapping often provides increased savings when compared to other forms of packaging, such as strapping, heat shrink film or ropes and lashing. As it sticks to itself, it also doesn’t require sealing accessories such as buckles, tools or heat machines.

The energy consumption while applying stretch wrap is lesser than when applying other systems.

Recyclable: new technology has led to the development of environmentally friendly films such as degradable pallet wrap. This allows you to make an environmentally conscious selection while still being able to wrap your goods securely.

Efficient: stretch wraps are efficient in providing better inventory management, worker productivity and enhanced packaging efficiency.

Versatile: the different types of stretch wraps available provide versatility to packaging. Those who have special packaging requirements are now able to find the wrap they require. Specialty wraps available include: coloured film, security film, pre-stretched film, degradable film, anti-static film, air flow film, UV film and many more.

What Is Stretch Film Used For?

Stretch film (also known as Pallet Wrap or Stretch Wrap) is a plastic film that is highly stretchable and is used mostly for packaging or palletising. Stretch films are tear resistant, have high tensile strength and good self-adherence, providing security and stability to the goods being wrapped.

Stretch film has several attributes, which make it perfect packaging material. These features include excellent transparency, ensuring better inventory management and high tensility, which keeps the objects packed and secure while being stored or transported. Some other features of stretch films include tear and tamper resistance, elasticity and protection from external pollutants like water and UV rays.

Stretch films are available in two main types, which differ in the way they are manufactured. One of these is Cast Stretch Film and the other is Blown Stretch Film. There are other specialised stretch films which are manufactured to meet different packaging requirements.

Cast Stretch Film: this is mostly used in automated or machine applications. It is made of thick material and it offers high adherence. This film is silent to apply and is high clarity to allow barcode scanning through the film.

Blown Stretch Film: This film is made through the process of blown extrusion, where the resin is melted and then blown. Although the cost of producing this type is higher, Blown Stretch Film is used for its high quality and tensility. Blown Film is known to be high tack extremely strong and stretchable in both directions.

Functions of Stretch Film

The functions of stretch films include:

  • Increase efficiency in handling and storing of different loads
  • Improve the stability of goods or products that have been packed; enabling better storage and transportation
  • Provide protection from dirt, dust and moisture
  • Offer a level of protection from being tampered or pilfered

Uses of Stretch Film

Stretch films find widespread usage in different industries like paper, plastics, and agricultural products, building materials, chemicals, metal appliances and food products. Bottle and can packages are also frequently secured tightly using stretch films.

Besides being used in these industries, stretch films are also used to secure packages for exports and foreign trade. Warehouses find the use of stretch films very handy as they help in ensuring that cartons remain on the pallet while being shifted and stored. Stretch films are also used in cargo tray packaging of goods like auto parts, electronics, metal products, wires and cables, and other daily necessities.

There are several manufacturers who produce different types of stretch films. One such company is Signet who makes the films onsite in Australia. Each film is made to the highest quality and Signet guarantees the lowest price – always. To view the full range or place an order, go to www.signet.net.au.

Comparing Shrink Wrap and Stretch Wrap

Packaging is an important function carried out in almost all businesses at one point or another.  Ideally, good packaging provides security, protection and identification for the goods.  For most consumer goods, shrink-wrap is the preferred choice for safe and strong packaging.  However, it is important to understand the difference between shrink wrap and stretch wrap to make sure you’re getting the right packaging solution for you.

The difference between a shrink wrap and a stretch wrap begins with their making. Shrink wrap is made from high quality and durable polyolefin plastic, so that when it is wrapped loosely around a product it will shrink when heat is applied. Stretch wrap is designed with polyethylene which allows the film to stretch around a load, holding it tightly together.

Another difference lies in the function that they serve. Shrink wraps and covers are used mostly to hold smaller items together, such as fast moving consumer goods.  This means it is used widely for items like stationery, toys, household articles, and equipment. This wrap can be used to wrap pallets, but not as commonly as stretch film. The advantages of shrink wrap includes being protective, water resistant, and its breathability.

Stretch wraps are designed for the transportation and storage of heavy goods, so are used mostly in packaging pallets of different goods, boxes or cans. This wrap is ideal as it can be stretched over/around the large boxes and crates, and is often tear or puncture resistant. As there are many requirements of pallet wrapping, stretch film is available in a range of specialties: Ultimate stretch film, Cast film, Blown film, Security wrap, Coloured wrap, Degradable wrap, Pre-Stretch wrap, Anti-Static wrap, Air Flow wrap and UV wrap. Some advantages of stretch wrap includes being protective, cost effective/economic and the wide range.

One trusted manufacturer and supplier of shrink and stretch films is Signet. Signet guarantees you high quality materials for low prices.

Your Guide to Stretch Film for Packaging

Stretch film (or stretch wrap) is a type of packaging which is used to wrap or pack cardboard boxes or other items so that they remain tightly bound when being stored or transported. Stretch film finds widespread usage in several industries where large amounts of goods have to be stored or transported. The tight packaging provides the goods with better protection and makes transportation easier. Stretch films also keep out dirt, dust and moisture, thereby protecting goods from getting spoilt. Being recyclable, stretch films provide an eco-friendly packaging option.

There are many types of stretch films, each designed for a different purpose. There are a couple of factors that determine which film to use – this depends upon the type and size of the load, the packaging requirements and your budget. Below are some of the various types of stretch films:

Cast stretch film: a glossy, clear and strong stretch film, the cast film is designed to stick to itself. The film unwinds quietly and has great clinging ability. It also has high clarity which makes it great for scanning barcodes or display uses.

Blown stretch film: the blown stretch film is manufactured by the process of blown film extrusion. This process makes it tear and puncture resistant as well as stretchable in both directions. The blown stretch film is ideal for packages having irregular shapes. It finds widespread usage in deep freeze storage. It is high tack and provides maximum efficiency while securing the pallets.

Machine stretch film: both cast and blown film are made into machine stretch film rolls which are designed to be applied using a machine. Machine film’s advantage is that it can be use more quickly and more efficiently when compared to hand-applied stretch film. The process is safer, more secure and reduces the costs of packaging materials when compared to hand films.

Pre-stretched film: stretch film that is stretched prior to wrapping a load is called pre-stretched film. The benefits of pre-stretch film is that it reduces the cost of packaging with lesser revolutions of film needed to wrap a load. It is more efficient, recyclable and is strong and consistent. This film is also OH&S friendly as the lighter roll prevents back, shoulder and arm strain.

Specialty stretch films: as the name indicates, these are specialty stretch films required for specific packaging needs. Specialty stretch films include Ultimate film, security wrap, coloured stretch film, degradable film, air flow stretch film, bundling film, and UV stretch wrap.

So, next time you’re in the market for stretch film products, consider your needs, and then decide which film would be best suited to them. Browse our full range of Stretch Film Products online today!

Cast Wrap vs. Blown Wrap: Which Pallet Film Is Best

Pallet Wrap - Cast vs Blown Wrap

It’s a common question we receive here at Signet, what’s the difference between our pallet wraps and which one is best for what application. In an effort to share our knowledge and make life easier for our customers, we decided to put together this short blog on which is which when it comes to the most popular hand pallet films.

Using pallet wrap is a great way to secure and protect palletised goods in transit. But which one should you use for your application? Although there are tens of different pallet wraps available on the market the two most common films used are cast and blown wraps. So what are the differences and when should you use what?

Cast Wrap

Cast Wrap is a versatile, ultra transparent film that is suitable for most pallet loads. The film is perfect for those proportioned pallet loads and offers excellent value for money with its lower price point. Cast Wrap is available in a range of thicknesses (um) and has excellent stretch capabilities to ensure the pallet load won’t lose shape during transit. The ultra clear nature of the wrap makes it perfect for applications where barcodes will need to be scanned through the wrap.

Blown Wrap

Blown Wrap offers a perfect solution for those bulky, heavy and awkward pallet loads. Its high stretch, tack and puncture resistant qualities ensure it will keep the heaviest of loads contained during transit. Available in a range of thicknesses (um), blown wrap should be used in place of cast film when loads are uneven, heavy or have sharp edges. Blown wrap also comes in solid white and black Security Wrap varieties for those sensitive loads. The Security Wrap keeps curious eyes away from your goods in transit and storage.

So in summary, Cast Wrap is perfect for those neat pallets and where barcodes are used, while Blown Wrap is great for all those ugly, bulky and sensitive freight situations. Hopefully this gives you an understanding between the two. If you would like us to cover any other products in our range, please let us know in the comments below.

Different Types of Stretch Films for Packaging

Stretch film or stretch wrap is a type of packaging, which is used to wrap or pack cardboard boxes or other items so that they remain tightly bound when being stored or transported. The stretch film finds widespread usage in several industries where large amounts of goods have to be stored or transported. The tight packaging provides the goods with better protection and easy transportation.

Stretch films are of various types, depending upon their usage. A particular kind of stretch film can be used depending upon the type and load size, the packaging requirements and the budget. Here are some of the various types of stretch films:

Cast stretch film

A glossy, clear and strong stretch film, the cast film has the attribute of sticking only to itself. It is made of a thick plastic material and is tear resistant. The film unwinds quietly and has great clinging ability. The cast stretch film is most popular in the food industry and is mostly used to package food materials.

Hand stretch film

The hand stretch film, as the name implies, refers to stretch film which is applied manually. The hand film too has good clinging capability. The use of the hand stretch film is limited to smaller packaging needs.

Blown stretch film

The blown stretch film is manufactured by the process of blown film extrusion. This type of film does not have clear optics, but it is hazy and dull. However, it has excellent puncture resistance. The blown stretch film unwinds noisily, but applies high force on the load. The blown stretch film is ideal for packages having irregular shapes. It finds widespread usage in deep freeze storage. It is tear resistant and provides maximum efficiency while securing the pallets.

Machine stretch film

The machine stretch film is the stretch film which is designed to be applied using a machine. The machine film is better than the hand film in the sense that it can be put on more quickly and more efficiently.

The machine stretch film is safer, more secure and reduces the costs of packaging materials when compared to hand films. There are several types of machine stretch films such as the cast machine stretch film, converted film and blown machine film.

Converted film

Stretch film that is stretched prior to wrapping a load is called converted film. The benefits of converted film are that it reduces the cost of packaging with lesser revolutions of film being used to wrap a load, it is more efficient, and it is recyclable and is strong and consistent.

Specialty stretch film

As the name specifies, these are specialty stretch films required for specific packaging needs. The specialty stretch films are of various types some of which are the tinted stretch film, heavy gauge film, roll wrap film, VCI stretch wrap, Pallet stretch film, bundling film, UVI stretch wrap and Opaque black stretch wrap. Stretch film wrapping provide the benefit of keeping the bundles together and provides them with enhanced protection and security. The damages to the packages are reduced when they are wrapped together.

Stretch films also keep out dirt, dust and moisture, thereby protecting goods from getting spoilt. Being recyclable, stretch films provide an eco-friendly packaging option. So, next time you’re in the market for stretch film products, consider your needs, and then decide which film would be best suited to them.

The Difference Between Stretch & Shrink Wrapping

Stretch and shrink wrapping are both materials used for the packing, protection and transportation of products. Just about every industrial, commercial or distribution company uses these products. Although these two types of wrapping may sound similar, they are in fact very different and have different occasions for use. So when it comes to wrapping, protecting and transporting, what are the differences between these two products and under what circumstances are they best used?

Stretch wrapping is a stretchable polyethylene plastic film that is wrapped tightly around a load. This type of wrapping is best used to hold loads together on a pallet during transportation and storage. The elasticity in the plastic holds the load together tightly, ensuring it does not move or become damaged.

This wrapping has many advantages. It is protective, cost effective and adaptable. The wrapping is secure and protects products form dust and moisture. Stretch film also comes in a variety of speciality wraps including UV, vented, anti-static and coloured stretch film so it can be used for a variety of applications. It is also a much more cost effective option for pallet wrapping. Although special equipment can be purchased for stretch wrapping to assist with the wrapping process, this equipment is cheaper than equipment for other types of wrapping.

On the other hand, shrink wrapping is a polyolefin plastics material that wraps loosely around a load and shrinks tightly when exposed to heat. This type of wrapping is usually used to protect a single product from dust or weather; or to tightly combine smaller items together. It is not commonly used to bind large pallets of products together.

A single layer of shrink wrap tends to be stronger than stretch wrap. If properly applied, shrink wrap should not chafe or damage during transportation or whilst being stored. It is also a good option for products needing ventilation. Shrink wrapping and the accompanying equipment tends to be more expensive than stretch wrapping but the end product looks more professional. Heating equipment can include heat guns, shrink tunnels and ovens.

So when it comes to packing and protecting your products ready for transportation and storage, choosing between stretch and shrink wrapping can make all the difference.
