Manufacturing method for compound bottle cap

Abstract

The invention relates to a manufacturing method for a compound bottle cap. The method comprises the following steps: preparing a basic material: adopting a common method to manufacture a common bottle cap according to the requirement of the merchant; gluing: applying glue on the outer surface of the common bottle cap; performing thermal treatment: putting the common bottle cap coated with glue into an oven; preparing an outer material, selecting the material and treating the material; compounding: compounding the manufactured material onto the surface of the common bottle cap and manufacturing a compound bottle cap; cooling: cooling the manufactured compound bottle cap at room temperature; polishing: polishing the cooled compound bottle cap; treating the appearance: preparing the appearance and pattern on the surface of the polished compound bottle cap; checking: spot-checking the qualification of completed products. According to the invention, a green safe protecting layer is compounded on the surface of the original common plastic bottle cap, so that the bottle cap can meet the food safety requirement; the investment price is low; the manufacturing method can achieve multiple purposes and is suitable for popularization.

Description

technical field [0001] The invention relates to a method for manufacturing a composite bottle cap, which belongs to the field of packaging manufacturing. Background technique [0002] With the acceleration of the pace of life, disposable plastic food boxes are widely used. The existing one-time plastic food boxes are made of polystyrene, which is foamed by adding ethane after high-temperature melting. Now the current Most of the plastic bottle caps use this method, but the disposable tableware made of this material has the following problems: the harmful substances in the plastic bottle caps will penetrate into the food, which is harmful to the human liver, kidney and central nervous system. etc. cause damage. However, if the raw materials for making bottle caps are completely replaced, or some special removal methods are added, the input price is not worth the loss, and there is no profit at all. Therefore, a manufacturing method for composite bottle caps is proposed on th...

[0002] With the acceleration of the pace of life, disposable plastic food boxes are widely used. The existing one-time plastic food boxes are made of polystyrene, which is foamed by adding ethane after high-temperature melting. Now the current Most of the plastic bottle caps use this method, but the disposable tableware made of this material has the following problems: the harmful substances in the plastic bottle caps will penetrate into the food, which is harmful to the human liver, kidney and central nervous system. etc. cause damage

However, if the raw materials for making bottle caps are completely replaced, or some special removal methods are added, the input price is not worth the loss, and there is no profit at all. Therefore, on the basis of ensuring low prices, a manufacturing method for composite bottle caps is proposed.
