Embodiment 1

[0023] The embodiment of the present invention provides a processing method for producing a one-time molding of plastic transparent outer packaging. The plastic transparent outer packaging uses polyethylene and polypropylene as raw materials, the weight ratio of polypropylene and polyethylene is 3:0.5, and the polypropylene material is The rigidity and strength are very high, and the toughness and aging resistance are relatively poor. After adding polyethylene, the material will become soft, the stiffness and strength will decrease, and the toughness and aging resistance will improve. The mixing of polypropylene and polyethylene makes the material very good. The toughness and rigidity can meet the needs of packaging, and at the same time, it has a certain toughness to improve the use effect of the outer packaging.

Embodiment 2

[0034] The embodiment of the present invention provides a processing method for producing a one-time molding of plastic transparent outer packaging. The plastic transparent outer packaging uses polyethylene and polypropylene as raw materials, and the weight ratio of polypropylene and polyethylene is 3:0.8. The mixed weight can make the processed product have good toughness and make the product softer when used, which is suitable for use in different packaging situations.

[0035] A processing method for producing one-shot molding of plastic transparent outer packaging, comprising the following steps:

[0036] A. The raw materials are dried. The polyethylene and polypropylene raw materials are cleaned and cut into granules. The particle size is 5 mm, and the mixture is uniform. The raw materials with large particle size can be quickly dried for processing, and then put into the dryer. During drying, water-absorbing resin is added to the raw materials, and the mixture is blown w...

Abstract

The invention provides a one-time forming processing method for producing a transparent plastic outer package, and relates to the technical field of one-time forming processing methods for producing transparent plastic outer packages. According to the one-time forming processing method for producing the transparent plastic outer package, the transparent plastic outer package takes polyethylene and polypropylene as raw materials, and the weight ratio of the polypropylene to the polyethylene is 3: (0.5-0.8). The drying machine is used for drying polyethylene and polypropylene raw materials, meanwhile, the drying efficiency of the raw materials is improved through arrangement of water-absorbent resin, the raw materials are fully dried in a high-frequency heating mode, and the product quality of transparent outer packages is effectively improved after moisture and volatile matter are fully volatilized. The raw materials are heated to a certain degree before entering the injection molding machine, the follow-up raw material melting time is shortened, the product machining time is shortened, the product quality is improved, the product efficiency is improved, and the injection molding machine is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of processing methods for producing one-shot molding of plastic transparent outer packaging, in particular to a processing method for producing one-shot molding of plastic transparent outer packaging. Background technique [0002] With the development of the economic market and the upgrading of commodities, the packaging market has also ushered in a major development. Now plastic packaging products are easy to process and can be flexibly applied to a variety of products, winning the favor of the bosses in the market. In the molding method, the molding objects are all plastic raw materials, which are processed by the flow of materials or large plastic deformation. [0003] When the plastic transparent outer packaging is produced at one time, the plastic raw materials are often of high moisture content or contain formaldehyde and other volatiles, resulting in poor quality of the processed products. At the same...
