Corrugated Plastic Sign Supplier introduces the calcium plastic corrugated box as a kind of packaging developed by using the excellent moisture resistance of calcium plastic material to replace the carton packaging on some special occasions.

Calcium plastic material is a composite material formed by adding a large number of fillers such as calcium carbonate, calcium sulfate, talc, etc., and a small number of additives to PP and PE resin (generally containing 50% resin and 50% CaCO, etc.). Because the calcium plastic material has the characteristics of plastic packaging materials, has the advantages of being moisture-proof, waterproof, high-strength, etc., it can be used for the packaging of frozen food, aquatic products, and animal meat products in high-humidity environments, reflecting the lightweight, beautiful appearance, cleanliness, durability and The advantages of dimensional stability. However, the surface of the calcium plastic material is smooth and easy to slip, the shock absorption and cushioning properties are poor, and the stacking stability is not good, and the cost is relatively high. The calcium-plastic material additives used for food packaging should meet the food hygiene requirements, that is, the non-toxic or toxic ingredients should be within the prescribed dosage range.
