Antibacterial plastic bottles for packaging

Patent name Antibacterial plastic bottle for packaging Patent applicant Shanghai Zihua Container Packing Co., Ltd. Principal Applicant Address 200240 Jiangchuan Road, Minhang District, Shanghai Inventor Dong Yong; Gu Junming Application (Patent) No. 200410054302.3 Application Date 2004.09.06 Certification Date Approval No. 1746081 Auditing Notice Date 2006.03.15 Instruction CD-ROM D0611-1 Main Classification No. B65D1/02(2006.01) I Classification No. B65D1/02(2006.01)I; B29C49/00(2006.01)I Division Original Application No. Priority The invention relates to an antibacterial plastic bottle for packaging and packaging, which relates to an antibacterial plastic bottle manufacturing technology and needs to solve the technical problem of making the product meet the requirements of an antibacterial plastic bottle. The present invention includes a high-density polyethylene, a low-density polyethylene, an antibacterial agent, and a double-screw hollow. The extruder heats, extrudes, and forms a preform through a die, characterized in that the preform is made of an outer layer raw material and an inner layer raw material, and a silver ion antibacterial agent soluble in a phosphate glass as a carrier is added to the outer layer raw material, and the antibacterial agent Agent particle diameter 3um ~ 5um, antibacterial masterbatch with low density polyethylene as the base material, according to the antibacterial masterbatch as the outer total weight of 5% of the ratio and high density poly The olefins are mixed into an outer layer raw material, and the heads of the inner and outer screw extruders are merged to form an outer layer of the preform containing the antibacterial agent; the outer layer of the preforms containing the antibacterial agent is blown, cooled, and formed in the mold. , remove the flash into an antibacterial hollow blow bottle. The invention is suitable for making packaging articles for various daily foods, medicines, cosmetics and washings. Sovereign matters 1. The use of high-density polyethylene, low-density polyethylene, and antibacterial agents for the packaging of antibacterial plastic bottles for packaging, heating, extruding and making of preforms through a die with a twin-screw hollow extruder, the preforms being blown in a mold Expansion, cooling, forming, characterized in that the preform is made of outer layer raw materials and inner layer raw materials, the inner layer is made of high-density polyethylene as the raw material through the screw of the inner layer of the extruder and heated and extruded; the outer layer raw materials are added with soluble phosphate Silver ion antibacterial agent with glass as carrier, antibacterial agent particle diameter 3um ~ 5um, antibacterial masterbatch added antibacterial agent, then add the antibacterial masterbatch weight 0.8% natural hydrotalcite discoloration inhibitor, and low density polyethylene Antibacterial masterbatch is formed on the substrate, and the antibacterial masterbatch is added to the raw material. At the same time, a 0.5% CT-50 composite heat stabilizer and 0.5% of the antibacterial masterbatch weight of the FB heat-resistant flame-retardant thermosetting phenolic resin are added to the raw material. The antibacterial masterbatch is 5% of the total weight of the outer layer. The antibacterial masterbatch is mixed with the high density polyethylene to form the outer layer raw material. The outer layer material is heated and extruded through the outer screw; the inner and outer screw extruders are machined. Head communion Preform made of die outer layer comprises an antibacterial agent; preform the outer layer comprises an antibacterial agent in the blow mold, cooled, molding, removing the burr into a hollow blow molded bottle antibacterial.
