Material selection of plastic single coil
Plastic single coils are mainly divided into three categories in the binding equipment industry: polyethylene resin (PE5000S), polypropylene resin (PP) and polyvinyl chloride resin (rigid PVC). Among them, polyethylene resin (PE5000S) and polyvinyl chloride resin (rigid PVC) have the largest market circulation. Due to the soft material of polyethylene resin (PE5000S), it is difficult to operate in manual binding, and the production efficiency is very low. The factory is also facing difficulties in recruiting workers or high wages, and slowly begins to retreat from the market; only the rigid PVC single coil has a "hard" characteristic, which reflects its easy processing and operation, thus achieving the purpose of [1] energy saving, Therefore, in the past two years, it has gradually been recognized by manufacturers in the industry, and the demand is also increasing.
