Some Frequently Asking Questions About Stretch Wrap

Wrapping goods with a very flexible plastic film is often constructed of linear low-density polyethylene (LLDPE). The items are securely bound by the elastic recovery.

Palletized goods are wrapped in stretch film to hold them to the pallet and to one another. Assisting in lowering worker injuries, discouraging load tampering, and lowering product loss. In our blog post, we go into further detail on the purposes of stretch film. Stretch film comes in a range of widths, thicknesses, and kinds.

The two most popular stretch film extrusion procedures are broken down here. Stretch film and other flexible plastic goods are produced via extrusion. For more information on the extrusion process, visit our blog.

Cast stretch wrap

Cast extrusion is used in its production. Thermoplastic material is melted and continuously extruded via a flat die onto a chill roll, where it is cooled and hardened using the cast extrusion method. 

The Cast stretch film benefits from this method by having outstanding clarity, requiring less energy to stretch, having increased tear resistance, silently unwinding from machines, and providing superior cling. Stretch films made by machines and by humans are both readily available.

Advantages of stretch wrap films 

Are you looking for a more effective approach to wrapping and safeguarding your loads? One of the most effective, adaptable, and affordable packaging options is a stretch film hand roll. When compared to the expense of potential damage during shipping and storage, using the proper pallet wrap is priceless. 

Stretch wrap is often drawn around the cargo and stretched into place to secure the goods on a pallet for transit or warehouse storage. The plastic has a "memory" and longs to shrink back to its original size, producing an elastic band effect that firmly secures the weight.

Cast stretch film is more widely used since it is more affordable than blown stretch film and has lower manufacturing expenses. Users can now see wrapped products thanks to improved clarity. Compared to blown stretch wrap, cast stretch wrap unravels more silently. Cast stretch film provides two-sided cling, allowing the wrap to be packaged safely.

Frequently asked questions about stretch film

  1. When do I use stretch film?

Stretch film typically holds boxes and merchandise on a pallet together for transit. Other uses for it include holding things together and safeguarding them during storage and transportation. There are numerous specialty films available for stretch film. UV stretch film, ventilated pallet wrap, colored stretch film, and anti-static stretch film are a few examples.

  1. How do I determine the appropriate stretch film size for me?

For diverse purposes, different thicknesses and widths of the film will need to be taken into account. Find the ideal thickness and width for your application using the chart below.

  1. What is an equivalent stretch film?

Stretch film created stronger, thinner stretch wraps as a result of higher petroleum prices. Because less petroleum resin is used in the production of this thinner stretch film, it is less expensive. The strength of the corresponding stretch film machine roll is increased using a multi-layered technology. 

The equivalent films are known by various names depending on the maker. Hybrid stretch film and Micron stretch film are the two equivalent hand stretch films that we provide. We also offer our Performance line of machine stretch film, which is stronger, thinner, and allows customers to save money. Stretch film, both hybrid, and micron is seen as an environmentally favorable solution for cutting down on film waste.

Hybrid stretch film

This stretch film is much thinner and made of an extremely durable resin. Although it is the lightest film we have, we do not advise using it for loads greater than 1800 lbs. The film does not have as much tear resistance as a thicker film because it is thinner.

Micron stretchable film

This stretch film falls between "true gauged" and "hybrid" stretch films. Excellent cling, stretch, and tear resistance are provided by this multi-layered film. It gives users the option to cut expenses while maintaining their load security confidence.

Performance machine stretch film 

That is our response to the increasing price of machine stretch film. A multi-layered machine stretch film, performance stretch film offers more stretch than conventional machine stretch film. It provides a lot of possibilities for downsizing and reducing.

  1. Are there any advantages to using opaque stretch film?

Over the transparent stretch film, the opaque stretch film has a number of benefits. Several advantages include:

1. By hiding goods in valuable packages, detours commit theft.

2. It aids in UV Ray product protection.

3. Prevents dust, dew, and rain-related damage.

4. Outlasts standard transparent stretch film when kept outside for an extended period of time.

5. Excellent for product color labeling.

  1. Is a UV stretch film necessary?

When the stretched film is kept in the sun, UV protection can help the stretch film last longer. When stored outside, the use of an opaque UV stretch wrap can lengthen the film's and the product's storage life. Any shipment that will be kept outside for more than 60 days should be considered for UV stretch.

  1. Are our shrink wrap and stretch film recyclable?

Stretch film and shrink wrap can both be recycled. Verify that soft plastics are accepted at your neighborhood recycling facility.

  1. Do I need a particular stretch wrap machine?

Any company wrapping more than 15 loads per day is advised to use stretch wrap machines. Stretch wrappers support a more stable and constant load while reducing waste and improving efficiency. For companies that stretch wrap fewer than 15 loads per day, there are many manual stretch film dispensers and devices available.

Out of the box, the extended core stretch film is ready and simple to use. It is great for companies that require stretch film but do not ship a lot of loads. Due to its simplicity of use, built-in braking mechanism, and capacity to securely fasten loads, two-handed manual stretch film dispensers are widely utilized.

  1. What is the pre-stretch film?

A standard gauge stretch film that has been stretched up to 90% of its maximum stretch rate is known as pre-stretch film or pre-stretched film. 

After being stretched by 90%, a typical 80 gauge stretch film becomes a 37 gauge stretch film. A little stretching is necessary during application because the stretched film is rolled onto cores.

  1. How to stretch-wrap a pallet?

Squeeze 8 to 10 inches of the end together to produce a rope shape after removing around a yard of plastic from the stretch film roll. Through one pallet corner, thread the rope portion. No knot is required. Start by wrapping the pallet's foundation. As the film is being peeled off the roll, wrap the pallet's bottom at least five times while maintaining a tight seal. 

Work your way up the box gradually, keeping a tight wrap in mind. The objective is for all the items to remain as a single unit. Push the top boxes once you've reached the top of the pallet to see if they move or if they combine with the bottom boxes. Wrap your way back down to the pallet's bottom if they start to move.

Conclusion

Efficiency is considerably increased by customizing the packaging that a product will be transported in. 

Wrapping packages will guarantee that there is no unused area where a product could potentially be broken or destroyed, as opposed to selecting a set of one-size-fits-all boxes or containers.
