Plastic mesh sleeves have the characteristics of strong toughness, simple and convenient packaging, and good adhesion, and are now favored by more and more precision workpiece manufacturers, glass product manufacturers, and fruit manufacturers. As plastic mesh sleeves are more and more purchased by the majority of manufacturers, there are also some unhealthy manufacturers in the market that use lower-priced plastic mesh sleeves that are mixed with raw materials. This will inevitably cause the plastic mesh sleeve to greatly reduce the abrasion resistance, flexibility and tensile properties. How to distinguish the quality of the plastic net cover? Here is how to identify high-quality plastic mesh sleeves.
The first is the combustion method: first, it is necessary to distinguish whether it is a thermoplastic or a thermosetting plastic. The thermoplastic plastic PP, PE, PC, PVC, PET, PETG, ABS, PMMA, POM, NYLONG, etc. that can be recycled are thermosetting plastics. If they cannot drip when heated, they are epoxy resin or silica gel. Dripping is polycyanamide, urine formaldehyde or acid-formaldehyde resin (can be understood as whether it can be recycled after heating).
The second is to subdivide each type of plastic. Under heating, thermosetting plastics can be epoxy resin or silica gel if they cannot drip, and melamine, urine formaldehyde or phenolic resin can drip. There are many types of thermoplastics. Mainly to subdivide common plastics.
