Problems solved by technology

When consumers use composite material packaging bags containing beverages, beverages are prone to overflow when tearing the mouth, which brings great inconvenience to consumers
At present, there is a packaging form with a socket on the market, which is welded on the inner layer of a pre-punched composite material with a piece of easy-to-puncture sealing material, which has good sealing and easy-to-puncture performance. It can only be realized by a special packaging forming machine for sealing, and additional auxiliary materials need to be added, so it is not easy to popularize and use

Abstract

The present invention relates to a composite material for beverage packaging bag into which the sucking tube can be easily inserted. Said composite material is made of more than two layers of materials and combining them together. In the composite material one layer is used as inserting hole at least, and another at least one layer is used as sealing layer of said inserting hole. Said invention is safe and reliable, and does not increase production cost.

Description

Technical field [0001] The invention relates to a packaging bag composite material, in particular to a packaging bag composite material into which a straw can be easily inserted. Background technique [0002] The usual flexible packaging composite materials are generally composed of a printing layer, a barrier layer, a reinforcement layer, and a sealing layer. The specific structure depends on the requirements of the packaging. Since the printing layer and the reinforcement layer are usually biaxially stretched films, the strength of the composite material is relatively high, and it is not easy to be torn and punctured. When consumers use composite packaging bags containing beverages, the beverages are likely to spill when they are torn, which brings great inconvenience to consumers. At present, there is a packaging form with a socket on the market. It is welded to the inner layer of the pre-punched composite material with a piece of easy-to-puncture sealing material, which has t...
