The Difference Between Plastic Wrap And Wrap Film

First, the nature is different
1, wrap film: the earliest PVC as the base material, DOA as a plasticizer and self-adhesive production of PVC wrap film.
2. Plastic wrap: a plastic packaging product, usually made of ethylene as the masterbatch through polymerization.
Second, different characteristics
1, winding film features:
(1) Unitization: This is one of the biggest characteristics of wrap film packaging. With the film's strong winding force and retraction.
(2) Primary protection: Primary protection: provide the surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of dust, oil, moisture, waterproof and anti-theft.
Especially important is the packaging film packaging to make the packaging force uniform, to avoid uneven force on the damage to the goods, which is the traditional packaging methods (binding, packaging, tape and other packaging) can not do.
(3) Compression firmness: The product is packaged through the retraction force after the packaging film is stretched to form a compact, space-free whole, so that the pallet of the product is tightly wrapped together, effectively preventing dislocation and movement. Products in transit. At the same time, the adjustable tensile force can make the product hard. Close, make soft products tight, especially in the tobacco industry and textile industry has a unique packaging effect.
(4) Cost saving: The use of winding film for product packaging can effectively reduce the cost of use, the utilization rate of packaging film is only about 15% of the original box packaging, the utilization rate of heat shrink film is about 35%, and the utilization rate of carton packaging is about 50%. At the same time, it can reduce the labor intensity of workers and improve the packaging efficiency and packaging grade.
2, plastic wrap features:
(1) Easy to be pulled out and cut;
(2) Easy to combine with glass ceramics and stainless steel masks (but the plastic wrap itself is not combined);
(3) Close to transparent without wrinkles, thickness varies;
(4) can withstand the general tension.
3. Different applications
1, winding film application:
(1) Food can be packaged directly.
(2) Single-sided viscous products can be manufactured to reduce the noise generated during winding and stretching.
(3) It is mainly used with pallets to pack scattered goods in whole sets, instead of small containers.
2, plastic wrap application:
(1) Cover food utensils to avoid bacterial infection.
(2) Packaged foods that are easy to keep (such as sandwiches).
(3) Refrigerate the soup bowl with plastic wrap to separate the oil from the soup.
Therefore, when you buy wrap film and plastic wrap, you must know what type you need to avoid bad problems caused by wrong purchase and wrong use.
