Polyvinyl chloride (PVC) is an initiator of vinyl chloride monomer (VCM) such as peroxide and azo compounds, or a polymer synthesized by free radical polymerization under the action of light and heat. It is a good material for garment bags, dustproof bags and packaging bags, etc.
A PVC Garment Bag consists of a hook, a layer board, a label pocket, the bottom of a plastic film bag and a lock catch, and it is a durable and reusable product that gives you the ability to keep your clothes dust-free, mold-free, bugs-free and wrinkle-free. Also, there’s no need for you to carefully fold clothes for better storage. These advantages make it widely-used in our daily life.
Technically, the PVC Garment Bag is a kind of plastic bag, only made with PVC film. Most PVC is synthesized by free radical polymerization through suspension, emulsion or bulk polymerization, in which suspension one is the major method, accounting for 80% of PVC production. During manufacturing, PVC bags need to be first put into high frequency heat pressing machines. To be more specifically, silk screen patterns, if have such needs, will be printed onto sliced PVC film, which will be under high-frequency heat pressure later. However, in this process, a tailored copper molding is needed. PVC Garment Bags are also open to recycle because they can be further made into PVC sleeve bags, zippered bags, packaging bags, hand bags and zip lock bags.
The features of specific resins, related agents and characters of pigments need to be taken into consideration during the coloring of PVC Garment Bags, but there are some other points for attention.
1. PVC resins will face a risk of thermal decomposition if encounter with some metal ions;
2. Pigments may have some influence on PVC properties.
