Medicinal plastic bottle and manufacturing method thereof

Abstract

The invention discloses a medicinal plastic bottle and a manufacturing method thereof, and belongs to the technical field of medicinal plastic bottle processing. The medicinal plastic bottle is characterized by being manufactured by the following raw materials in part by weight: 95 parts of polyethylene, 5 parts of polypropylene and 4 parts of color concentrate. The manufacturing method is characterized by comprising the following steps of: 1) adding the polyethylene, the polypropylene and the color concentrate into a mixer; (2) uniformly mixing the materials in the mixer to obtain a mixture; (3) molding the mixture into a blank by injection; (4) molding the blank by blowing; and (5) de-bottling. dhpe / pp raw materials are adopted and the raw materials are fully and uniformly blended, so the bottle wall is uniform, the permeability resistance is high, the shelf storage period of filled medicaments is long, materials are saved and the cost is reduced. The manufacturing method has the advantages of high production efficiency and short period; and compared with a two-station 'pouring-blowing' process, the manufacturing method can realize fully automatic counting and packaging.

Description

technical field

[0001] The invention provides a medical plastic bottle and a manufacturing method thereof, belonging to the technical field of medical plastic bottle processing. Background technique

[0002] Plastic bottles fill almost every aspect of our lives, especially plastic bottles for medicine. The plastic bottles we produce are only a small part of them, but they must meet their requirements for transparency, color, safety, airtightness, etc. Special requests are not an easy thing to please. In addition to studying the structural design and manufacturing process of the product, the formula design of the product is also a very important aspect. The pure use of PE resin cannot meet the requirements of the product, and it is necessary to look for some additives and additions that can modify the resin. Quantitative process to improve the appearance quality and physical and chemical properties of plastic bottles, high-quality plastic bottles with stable physical and che...
