Problems solved by technology
In addition, PVC scrap companies cannot use it themselves, and the recycling price is very low, which increases the production cost of the company.
Another reason is that PVC recycled materials are easy to pollute other plastics, so extra attention must be paid in production, which brings some troubles to production operations. As plastics are used more and more widely, it is urgent to develop products that can balance the rigidity and toughness of products as needed. , to optimize cost, but also has extremely high toughness and impact resistance, and is suitable for thermoformed food packaging with high dimensional stability, such as beverage cups, salad plates, deli plates and lunch boxes with lids, etc. material

Embodiment Construction
[0024] A low-temperature-resistant plastic composite sheet for food cups, characterized in that it is a four-layer sheet with a layered structure arranged in sequence according to layer B / layer A / layer B / layer C;
[0025] The layer A is made of the following raw materials in parts by weight: high-impact polystyrene blend 25, recycled material 207, thermoplastic rubber 15, color masterbatch 4.5, accounting for the total weight of the sheet by weight percentage 71.5%;
[0026] The layer B is made of the following raw materials in parts by weight: high-impact polystyrene blend 100, color masterbatch 4, accounting for 26% of the total weight of the sheet by weight percentage, four-layer sheet structure The two layers of layer B in each account for 13% of the total weight of the sheet;
[0027] The layer C refers to being made of general-purpose polystyrene, accounting for 2.5% of the total weight of the sheet by weight percentage;
[0028] The high-impact polystyrene blend is ma...

Abstract
The invention discloses a low-temperature-resistant plastic composite sheet for food cups. The low-temperature-resistant plastic composite sheet for the food cups is of a four-layer structure including a layer B, a layer A, a layer B and a layer C in sequential arrangement. Rigidity and ductility of products can be balanced according to needs so that cost is further optimized, the low-temperature-resistant plastic composite sheet for the food cups has extremely high ductility and impact resistance, can be used at minus 30-20 DEG C and is recyclable, and product cost is reduced.
Description
technical field [0001] The invention relates to the field of plastics, in particular to a low-temperature resistant plastic composite sheet for food cups. Background technique [0002] Since the traditional BOPS and PVC sheets need special equipment for production, most of the BOPS and PVC sheets required by general thermoforming enterprises are outsourced. In addition, the PVC leftovers cannot be used by the enterprises themselves, and the recycling price is very low, which increases the production cost of the enterprises. Another reason is that PVC recycled materials are easy to pollute other plastics, so extra attention must be paid in production, which brings some troubles to production operations. As plastics are used more and more widely, it is urgent to develop products that can balance the rigidity and toughness of products as needed. , to optimize cost, but also has extremely high toughness and impact resistance, and is suitable for thermoformed food packaging with...
