Choose the right packaging film according to your needs

Having the right packaging film can make a world of difference when it comes to your packaging needs. From wrapping items with the right type of wrapping paper to choosing the right size wrapping film for your needs, you need to make sure you have everything you need to get the job done right.
Stretch Wrap VS Shrink Wrap
Those in the business of packaging and displaying merchandise often have to choose between stretch wrap and shrink wrap. These two types of plastic packaging may appear to be the same, but there can be considerable differences between them.
The main difference between the two is that stretch wrap is designed to hold a load together while shrink wrap is designed to secure a load, whether it is a pallet, box or individual items.
Stretch wrap is a lightweight film that secures itself tightly to the load it is wrapping, making it ideal for palletizing. Stretch wrap can also be used to protect items from moisture, UV rays, and dust. It also allows for ventilation, which helps reduce the chance of moisture damage.
Shrink wrap, on the other hand, is a thicker plastic film that shrinks under load. It is applied loosely to the product, then heated to shrink the film into a more snug fit.
There's a lot to like about shrink wrap, which is why many businesses are turning to this more durable material. Unlike stretch wrap, shrink wrap can be applied manually using a heat gun or automated machines.
It's also worth noting that while shrink wrap is often associated with food packaging, it can also be used to protect outdoor furniture. It also helps reduce worker fatigue.
The best way to make the right decision is to understand the different types of packaging available to you and which type best suits your needs. The decision should be based on what you are going to use it for. If you're not sure which one to choose, here's a guide to help you make the best choice.
The key to comparing stretch wrap vs shrink wrap is determining what you will be using it for. This will help ensure you get the most value from your investment. Using the right equipment can also save you time and money. This is especially true if you wish to upgrade legacy packaging systems.
Stretch Film with High Slip and Single Side Adhesion
Various types of stretch films are used for packaging products. These include: cast stretch film, blown film and pre-stretched film. Although these types have different properties, they are primarily used for one purpose: to hold products together.
Cast stretch films are produced using a cast extrusion process. This method of producing stretch film is more affordable than blown film, but is less resistant to tearing. Cast film is also double-sided adhesive, which means that even if the products are not adhered to each other, the film will hold them together.
The blown film has high strength and is not easy to tear, but the transparency is poor. Blown film is also more expensive. They're better suited for sharp-edged products, but can also produce a distracting sound when stretched.
Pre-stretched film is lighter than conventional stretch film. It's half the thickness and more manageable. It can reduce costs by up to 40%. It is also easier to apply and requires less labor. The film is also twice as strong as conventional stretch films.
In order to obtain a high degree of adhesion, adhesion additives should be used. Cling additives are liquids that are injected into the stretch film resin. These liquids are usually polyisobutylene. Additives are usually added uniformly throughout the film. Additives were added to the adhesive layer of the film, accounting for 15% of the total weight of the film. Additives should have a minimum tensile capacity of about 20%. It should also be evenly dispersed throughout the film to ensure that it remains in adhesive contact with the non-adherent layer.
Another way to measure the stretchability of a stretch film is to use the dart drop test. This test measures the strength of the film at the point of puncture. The number of drops required to pierce the film may vary, but the recommended minimum level is five drops.
Another way to measure the non-stick properties of a film is to calculate the dynamic coefficient of friction. A coefficient of friction less than 1.0 indicates relative motion. A coefficient of friction greater than 2.0 indicates unfavorable sliding properties.
Outer packaging is not suitable for all types of products. It works best for products that are flat, easy to pack, and can be bundled with other products. The outer packaging can also provide other packaging details, such as barcodes, without obscuring them. It can also help suppress strong odors.
When comparing the cost of outer packaging versus shrink wrap, the difference can be significant. Overpacks cost about 15-28p more per piece. Depending on the size of the load, the cost can be much higher.
In terms of energy saving, outer packaging is not as cost-effective as shrink wrap. Unlike shrink wrap, overwrapping is a mechanical process that requires specialized equipment. It also requires specific packaging machines.
Packaging is also an aesthetic process, and it does have its advantages. It helps keep dirt and dust out of the packaging and also helps prevent tampering. This helps protect the packaged product from damage during shipping. Outer packaging also helps keep product packaging clean, which is critical to maintaining food safety standards.
Unlike shrink wrap, the overwrap uses polypropylene film, which is less expensive than polyethylene. Polypropylene does not shrink and is therefore more flexible than polyethylene. It's also better water and grease repellent to help keep the pack clean and protected.
Shrink wrap is a more cost-effective form of film packaging than overwrapping. It also has better durability and uptime performance. It's also faster and more reliable. Stretch wrap can also reduce film costs by as much as two-thirds. It's a good choice for oddly shaped products. It is also a good choice for uneven products.
