Abstract
The invention discloses a plastic composite sheet for a food cup. The plastic composite sheet is in a layered structure and comprises four layers including a layer B, a layer A, a layer B and a layer C which are arrayed in sequence. The plastic composite sheet can balance the rigidity and the toughness of the product according to needs so that the cost product is lower, has extremely high toughness and impact resistance, can be used at 20-30 DEG C below zero and can be recycled so that the cost of the product is reduced.
Description
Technical field
The present invention relates to plastics field, is exactly a kind of food cup composite plastic sheet.
Background technology
Because needing special equipment, traditional BOPS, PVC sheet material produce, so generally mostly the thermoforming required BOPS of enterprise, PVC sheet material are outsourcing.In addition PVC leftover pieces enterprise oneself cannot utilize, and reclaims price very low again, has increased the production cost of enterprise.Another reason is that PVC reclaimed materials easily pollutes other plastics, therefore to especially note aborning, this just serves trouble along with plastic applications is more and more extensive to production operation band, urgent need will be developed rigidity and the toughness of equilibrium product on demand, cost is more optimized, also there is high toughness and impact resistance simultaneously, be applicable to the thermoforming packaging for foodstuff of high degree of dimensional stability, as the novel plastic sheet material of goblet, salad plate, prepared food dish and cutlery box with cover etc.
Summary of the invention
The object of this invention is to provide a kind of high toughness and impact resistance, be applicable to the thermoforming packaging for foodstuff of high degree of dimensional stability, as the food cup composite plastic sheet of goblet, salad plate, prepared food dish and cutlery box with cover etc.
Above-mentioned purpose realizes by following scheme:
