Evaporated coated packaging bag and production process thereof

Abstract

The invention relates to an evaporated coated packaging bag. The evaporated coated packaging bag comprises a bag body which is used for loading medicine and made of complex film in a hot melting mode.A plastic layer, a printing layer, a flexible layer and an outer surface layer are arranged on the complex film in sequence from the inside to outside of the bag body. The plastic layer is made of GLevaporated film. The printing layer is formed by spraying printing ink to the surface, close to the flexible layer, of the plastic layer. The flexible layer is made of PE thin film, and the outer surface layer is made of HDPE thin film. Visible windows communicating with the plastic layer and the flexible layer are formed in the printing layer and arranged at the bottom of the bag body. The evaporated coated packaging bag provided by the invention has the effects that the humidity resistance is good, the plasticity is high, and the medicine in the bag is convenient to observe.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a steam-coated film packaging bag and a production process thereof. Background technique [0002] Medicine bags are commonly used medical consumables in hospitals. Medicine bags are mainly used to hold medicines. Usually, medicine information is printed on the outer surface of the medicine bags. Due to the strict packaging requirements of pharmaceutical products, medical bags need to have moisture-proof and anti-corrosion requirements. Otherwise, due to the proliferation of microorganisms, the medicines will become mildewed and lose their original value. Existing pharmaceutical packaging bags generally use paper bags, plastic bags or aluminum foil bags. Paper bags are prone to moisture and are difficult to load liquid medicines; general plastic pharmaceutical packaging bags have better moisture-proof performance, but the commonly used plastic materials are softer and les...

AI Technical Summary

Problems solved by technology

Existing pharmaceutical packaging bags generally use paper bags, plastic bags or aluminum foil bags. Paper bags are prone to moisture and are difficult to load liquid medicines; general plastic pharmaceutical packaging bags have better moisture-proof performance, but the commonly used plastic materials are softer and less plastic. It is difficult for the user to level the surface and spread the medicines; although the aluminum foil bag has strong plasticity, it is opaque, and it is difficult for the user to observe the stock of medicines in the bag through the surface, which is not convenient enough
