If you have recently started to increase the production at your manufacturing facility, then you may have begun shipping out large volumes of your products on pallets. This is one easy way to get your items out the door in bulk. However, the products may not always stay put on the pallets during the shipping process. If you want to reduce damage and loss concerns, then it is wise to invest in a pallet wrapper that will allow you to secure wrap around the palleted products. Many pallet wrapping systems are automatic varieties that wrap the products once you turn the unit on. However, you will need to purchase the right type of wrap for your unit. Keep reading to learn about some of the options available to you.

Stretch Wrap Vs Stretch Film

Before you pick up any sort of wrap for your wrapper, you should know the difference between stretch wrap and stretch film. Stretch wrap is the highly elastic and flexible film that is layered around a pallet. The material is made from linear low density polyethylene. This material is a polymer based plastic that can be stretched significantly without causing stress to the polyethylene itself. 

Stretch film is the other type of wrapping material and it is often called shrink film. This is the type of thick polyolefin plastic that is wrapped over the products and the pallet. The film is then heated to shrink it over the palette to keep the items secured. Only a single layer of the material is used to create the protective barrier and it is often used to secure loose and heavy items, like wood. However, it is not used with a wrapper machine. 

Wrapper machines require you to purchase rolls of stretch wrap, so make sure you are buying the right type of material.

Blown Stretch Materials

Now that you know that you need stretch wrap, you will need to pick from a few different types. The types are based on the manufacturing process used to create the material. Blow stretch wrap involves a blown extrusion process where the polyethylene is spread onto a die. Once the material is secured on the mold, air is blown into the material, and it is then left to cool. This creates a sort of bubble in the polymer. Air dissipates throughout the polyethylene as it cools. The result is a tough wrap material that is resistant to rips and tears. The material is also able to withstand heavier loads and more stress.

The advantage to this material is that the polymer retains a sort of memory that keeps the film from overstretching or weakening over time. This helps the keep products secured to pallets. This is advantageous for long term storage purposes. Also, the strength makes the blown wrap ideal for any products that are sharp or have strong angles and edges. 

The drawback to this type of wrap is the expense. It is more expensive than other types of wraps and this can greatly increase your shipping and packing expenses.

Cast Stretch Materials

The other common wrap option you can choose from is cast stretch wrap. This material is not as strong and sturdy as blown wrap, but many types of products do not require the strength and resiliency of blown polyethylene. Cast stretch wrap may not be as strong, but it does have some distinct advantages. It is cheaper than blown wrap materials and it is highly flexible. The wrap material also clings on both sides, which means that it sticks in place much more aggressively than other types of wrap. 

Cast stretch products also stretch more easily than other types of wraps and this makes wrapping with a machine easy and quick. There are two types of cast stretch wraps to consider. These include machine and hand made varieties. Machine grade wraps are cheaper, but hand made ones are a bit stronger.
