AI Technical Summary

Benefits of technology

This patented technology solves problems associated with current commercial dairy product packages such as poor air tightness during storing due to exposure to humidity while still allowing some types of lactic acid producing microorganisms (such as Lister) to affect their quality. Additionally, this package design allows for longer periods without losing any protective features like watertightness, gas permeability, etc., resulting in better preservation times than previous designs. Overall, these technical improvements improve the functionality and lifespan of commercially available dairy products stored at room temperature.

Problems solved by technology

This patented problem addressed by this patents relates to improving the design of packages made from flexible material such as woven or knitted fabric. These designs allow airflow while still keeping out any harmful substances present on them.

Abstract

The invention provides a packaging bag and application thereof. The packaging bag comprises a packaging bag opening part and a packaging bag body, wherein the packaging bag opening part and the packaging bag body are integrally connected; internal folded wires which are sunken towards the inner side of the packaging bag body are arranged at the connection part of the packaging bag opening part and the packaging bag body; a sealing bonding strip which can perform sealing multiple times is arranged below the packaging bag opening part; zigzag tearing wires are arranged on the outer side of the packaging bag body; tearing wire pull heads are arranged on the tearing wires; the packaging bag opening part and the packaging bag body are composed of a plastic film layer and an outer layer; the outer layer is arranged on the outer side of the plastic film layer; and the tearing wires are arranged on the outer layer. The packaging bag has the beneficial effects that a plastic film is prepared through adopting the seven-layer coextrusion blow molding manner, the shelf life of industrial milk powder can be effectively prolonged through the packaging bag prepared through the film, the milk powder does not go bad within 3 to 6 months and even 12 months, the shelf life of industrial milk powder is prolonged, and the storage time of industrial milk powder is effectively prolonged.
