You probably have experienced a product wrapped using shrivel wrap over your lifetime. This is a type of plastic film wrap that shrinks tightly over the product that it is covering. People prefer using it due to its versatility and ability to hold up to pressure. Read through this article to learn a couple of facts related to industrial shrink wrap.
The product varies in composition. The most common type of shrivel wrapper is the polyolefin. It varies in thickness, strength, and shrivel ratio. There are other types made out of PVC, polypropylene, and polyethylene. Lamination and co-extrusion are used for construction and manufactures can have more than five layers of cross-linked composition.
There are two types of manufacture products. You can find this product as one-directional or dual- directional. The one direction contains a unidirectional and a mono-directional. The manufacturing process involves stretching the films to orient the molecules at their original pattern. Cooling the film will set the particles at that position until one decides to reheat it.
Shrink film machines has a lot of variation as well. If you intend to buy shrink wrapper machines, you have to choose one that matches your needs. They differ according to the packaging speed, type of product they should wrap, and according to the space that one has. Make sure that you assess these requirements before you pick your machine.
There is a difference between condense and stretch wraps. The shrink film is a sealant that requires heating to hold its product. On the other hand, a stretch film stretches around a load to create tension that protects the product from shifting while in transit. Condense films are ideal for packaging whereas stretch film works for transportation of large loads when they need shipping over a long distance.
You can pick different products based on condense percentages. Bi-axially oriented film varies according to their percentage. You can alter its rate from 40/40 to 20/20. Your choice depends on the type of product that you intend to pack, and the level of condensing that you want to achieve. You can also find free shrink that performs better in products with difficult sizes and shape.
You have to be careful with the resistance to tear and puncture. This is the level of resistance that the film can maintain when punctured or exposed to tear. Films with high resistance to puncture have a lower resistance to tear and the vice versa. For products such as window boxes, having resistance to puncture is crucial. However, the best film should have a balance between tear and puncture for convenience. Store the product in a cool place to avoid weakening the film, which makes it weak.
Understanding the characteristics and features of a condense film provides an excellent opportunity to make the best out of your expenses. However, consult your supplier to get relevant information about your needs and the machine that fits you, if you intend to buy one. You should also assess the capacity of the product in small scale before you purchase large supplies.
