Calcium plastic box is a kind of high-density polyethylene (HDPE) as the main raw material, calcium carbonate as filler, and add a variety of additives to make of the box, the following will be from its performance characteristics, application fields, processing technology and other dimensions of a detailed introduction:
Performance characteristics:
Good physical properties: The calcium plastic box has the characteristics of light weight and high strength, can withstand certain pressure and impact, is not easy to deform and break, and can effectively protect the contents. At the same time, it has good rigidity and can maintain a stable shape, which is convenient for stacking and transportation.
Excellent moisture and water resistance: The product has very low water absorption, can resist the intrusion of moisture, can stay dry even in humid environments, and prevents the contents from deteriorating due to moisture, which makes it particularly suitable for product packaging with high requirements for moisture resistance.
Strong chemical stability: calcium plastic box has good resistance to acids, alkalis, salts and other chemicals, is not easy to be corroded and eroded by chemicals, and can be used to package products containing chemicals, such as pesticides, chemical reagents, etc.
Good thermal insulation: It has certain thermal insulation properties, which can block the transfer of heat to a certain extent, help to keep the temperature of the contents stable, and is suitable for temperature-sensitive product packaging.
Environmentally friendly and recyclable: the calcium plastic box can be recycled and reused, which meets the requirements of environmental protection and reduces the pollution to the environment. After the waste calcium plastic box is processed, it can be reprocessed into new calcium plastic products, reducing the waste of resources.
Fields of application
Food packaging: Because the calcium plastic box is non-toxic, tasteless, good hygienic performance, not easy to mold, and strong corrosion resistance, it can be used for food packaging, such as fruit, vegetable, seafood, meat, etc., which can effectively extend the shelf life of food and maintain the freshness of food.
Pharmaceutical packaging: The product has the characteristics of moisture-proof, waterproof and strong chemical stability, so that it can well protect the drug from moisture and deterioration, ensure the quality and safety of the drug, and is often used in the packaging box of the drug and the outer packaging of the medicine bottle.
Daily necessities packaging: In the field of daily necessities, such as cosmetics, detergents, stationery, etc.
Industrial packaging: calcium-plastic boxes can be used for the packaging of industrial products, such as hardware tools, mechanical parts, electronic components, etc., which can play a role in protecting products and facilitating transportation and storage.
Other fields: It can also be used in postal, logistics and other industries, as express packaging, turnover boxes, etc., its reusable characteristics reduce packaging costs and improve logistics efficiency.
Processing technology
Raw material mixing: High-density polyethylene (HDPE), calcium carbonate and various additives are mixed in a certain proportion to ensure that the components are evenly distributed and ready for subsequent processing.
Plasticizing extrusion: The mixed raw materials are heated and plasticized by an extruder to make them into a fluid melt, and then extruded through the mold to form a calcium-plastic sheet or calcium-plastic sheet.
Calendering: The extruded calcium-plastic plate or sheet is calendered by a calender to make its surface smoother and thicker thickness, while improving its density and strength.
Slotting and crimping: according to the size and shape of the need, the calendered calcium-plastic board or sheet is grooved and crimped for subsequent folding and molding.
Printing and binding: The printing process is used to print the required text, pattern and logo and other information on the surface of the calcium-plastic box, and then the slotted plate or sheet is folded into a box shape through the binding process, and fixed with glue or other binding materials to form a complete calcium-plastic box.
