Problems solved by technology

However, the industrial release agent coated on the mold will adhere to the PVC film, and after the PVC film with the industrial release agent is made into fruit packaging, it will adhere to the fruit, which will cause uncontrollable health risks to the human body; and After several hours of refrigeration, a large amount of water mist will condense on the fruit packaging. For fruits with a short shelf life, such as strawberries, cherries, mulberries and red bayberry, etc., they will be sprayed by water droplets. It is very perishable after arrival, and when water mist (water droplets) are attached to the inner wall of the fruit packaging box, it will affect the aesthetics of the packaging box

Abstract

The invention relates to a refrigerated water mist-free PVC adhesive cloth and a preparation method thereof. The raw materials for the preparation of the refrigerated water-free PVC tape include PVC powder, epoxy soybean oil, methyl methacrylate-butyl acrylate copolymer, stabilizer, KM-9737A, modifier and lubricant. The refrigerated and mist-free PVC adhesive sheet of the present invention can effectively prevent its rupture during plastic-absorbing processing, has the advantages of easy demoulding during plastic-absorbing molding, and is not easy to damage molds and finished products, and can be refrigerated without water mist after molding. The preparation method of the invention is very simple, has high production efficiency, low production cost and good economic effect. In addition, the refrigerated water mist-free PVC tape of the present invention has uniform thickness distribution, good flattening property, good formability, good mechanical properties, and good glossiness.

Description

technical field [0001] The invention relates to the technical field of packaging films, in particular to a refrigerated non-mist PVC adhesive tape and a preparation method thereof. Background technique [0002] The PVC plastic fruit packing box is a box for packing fruit, which is convenient for the transportation, preservation and sale of the fruit, and plays a role in beautifying the fruit. The fruit packing box generally has commodity information, such as production date, shelf life, barcode, instructions for use, manufacturer Telephone, address and other information is convenient for the handling and transportation of goods, and at the same time, it can also protect the damaged goods and keep the goods fresh. [0003] The common PVC plastic fruit packaging box is based on PVC plastic film, and the PVC film plastic is put into a vacuum suction machine for plastic forming. Ordinary PVC plastic films have particularly poor release properties during blister molding, which w...
