Stretch film is a packaging product mainly based on LLDPE substrate. It can be packaged manually or with a winding machine. We usually see it in some large-scale transportation or logistics freight. The stretch film is on the outside of some goods or packaging. One or more layers of film have very good stretchability, mainly for protection.
First, we need to know that sealed packaging is different from full-width packaging.
1. Sealed packaging: This kind of packaging is similar to shrink film packaging. The film wraps the pallet around the pallet, and then two heat grippers heat seal the two ends of the film together. This is the earliest form of use of stretch film, and has developed more packaging forms;
2. Full-width packaging: This packaging requires that the film width is sufficient to cover the tray. The shape of the tray is regular, so it is suitable for use, and the suitable film thickness is 17 ~ 35μm.
Packaging advantages about stretch film
1. Beautiful packaging; the product is packed together with the retraction force after the stretch film is stretched. The whole unit that does not take up space, tightly wraps the product trays together, can make the hard products close, and make the soft products shrink, especially when the electronic products are shipped or the textile industry has a unique packaging effect.
2. Good fixation; this film has super strong winding force and retractability, which compactly and fixedly bundles the product into a unit, so that the scattered small pieces become a whole, even if the product is not loose in unfavorable environment Separated from, and without sharp edges and stickiness, so as not to cause damage.
3. Cost reduction: Using stretch film for product packaging can effectively reduce the use cost. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grade.
4. Good protection performance; stretch film forms a very light, protective appearance around the product, so as to achieve dustproof, oil-proof, moisture-proof, waterproof, anti-theft purposes. The most important thing is that the stretch film packaging can make the packaging The products are uniformly stressed to avoid damage caused by uneven forces. This is not possible with some strapping and packing tapes.
