Embodiment Construction

[0012] From the accompanying drawings, we can see that the process flow of the present invention is equipped with high-density polyethylene and antibacterial agent-containing raw materials according to the inner and outer layers respectively, adopts twin-screw extruder to heat and extrude, and is made into a preform by a die, and then The preforms are inflated, cooled, and formed in the mold, and the qualified products are packed into boxes after the auxiliary device removes the product flash, and the defective products are scrapped and crushed.

[0013] In the present invention, the preform is made of the inner layer raw material and the outer layer raw material respectively, and the inner layer raw material high-density polyethylene is heated and extruded by the inner layer screw extruder; silver ion antibacterial agent is added to the outer layer raw material, and the particle diameter of the antibacterial agent is 3um ~5um, the antibacterial agent uses soluble phosphate gla...

Abstract

An antibacterial plastic bottle used as the package of food, medicine, cosmetics and detergent is prepared from high-density polyethene, low-density polyethene and antibacterial agent composed soluble phosphate glass as carrier and Ag ions as active component through preparing the raw material containing antibacterial agent for external layer, preparing the raw material (PE) for internal, respective heating, co-extruding out via dual-layer die while blowing to obtain dual-layer bottle blank, cooling and trimming.

Description

Technical field: [0001] The invention relates to the manufacturing technology of plastic hollow blow molding containers, especially the manufacturing technology of antibacterial plastic bottles. Background technique [0002] The plastic hollow blow molding bottle uses high-density polyethylene (HDPE) as raw material, is heated and extruded by an extruder, and is molded into a preform through a mouth. The preform is inflated, cooled and formed in the mold. Serve as a hollow blow-molded bottle. Plastic bottles produced by this method do not have antibacterial properties. [0003] Sanitation and disinfection products are indispensable supplies in people's daily life. However, there are only antibacterial blow-molded packaging film products on the market at present, and there are no antibacterial hollow blow-molded products. [0004] During the frequent use of sanitation and disinfection products, harmful viruses and bacteria continue to mutate, forcing people to continuously...
