Problems solved by technology

[0002] With the development of science and technology and the upgrading of global environmental protection requirements, in addition to the requirements for the hygiene, safety and comfort of plastic products, plastic products must also be reduced, thinned, recyclable and degradable. The main materials are PVC, thermal paper composite polyethylene and Dupont paper; but the above materials have certain problems: the glass transition temperature of PVC is 77-90°C, and it begins to decompose at around 170°C, and its stability to light and heat is poor. Above ℃ or exposed to sunlight for a long time, it will decompose to produce hydrogen chloride, and further autocatalyze and decompose, causing discoloration and rapid decline in physical and mechanical properties. The material is highly corrosive to the screw mold, so it is necessary to choose a corrosion-resistant screw mold; at the same time, PVC is the main source of dioxins and belongs to the 3 types of carcinogens; the density of PVC is greater than 1.4g / cm 3 , high unit cost, poor air permeability, and not resistant to alcohol
Heat-sensitive paper compounded with polyethylene has the disadvantages of hard material, poor hand feeling, airtightness, many processes, high cost and not easy to recycle.
Dupont paper is expensive and has poor softness
Therefore, the material of above-mentioned disposable medical wrist strap can not satisfy the demand of market
