In the process of film processing, a raw material is extruded to another thin film which has been made, or the different kinds of thin films have been bonded to each other to form multilayer film. The product is called composite membrane. The material of the composite film is mostly plastic, but it can also be made of paper, metal foil (usually aluminum) or fabric. The basic requirement of the composite membrane is that there is a good bonding between the layer and the layer to ensure the overall mechanics of the packaging.
|Poly bubble mailers
Poly bubble mailers, which is characterized by temporary package to be transferred in a variety of vehicles, parcel will be stacked with each other, squeezing. Poly bubble mailers can be divided into ordinary plastic bags, paper envelopes, bubble envelopes, Poly bubble mailers, woven bags and so on.
Ordinary plastic bags are made of low-density polyethylene, there is also a high-density polyethylene, a large amount of Poly bubble mailers, light weight, small size, attached to the package weight and small size, ideal for less demanding products to transportation such as clothing, footwear, jewelry, and other debris.
Courier envelope document mainly paper, divided into white paper, white card, cardboard and other cattle, paper surface usually covered with a layer of plastic film, and waterproof for added strength.
Courier bubble mailers, mostly plastic, lined with polyethylene bubbles, the outside layer of PET composite film or kraft paper, these bags lined with bubble has its cushioning effect, to better protect the bag of goods, but also pad It has a certain insulation, thermal insulation effect.
The mailers packaging mainly including the mailing bags, bubble mailers and padded envelopes.
The mailing bag is a general designation, which included may kinds of materials and many kinds of structures, the materials including the PE, PET, OPP, PVC, Aluminum, stell, paper etc. the structures including single layer, double layers and multiple layers.
