Unidirectional double-face valve type inflating packaging bag

Abstract

The invention relates to the field of protection devices for object transportation and particularly relates to a unidirectional double-face valve type inflating packaging bag. The unidirectional double-face valve type inflating packaging bag comprises a packaging bag body and an air valve, wherein the air valve comprises an upper membrane, a lower membrane and an air valve membrane; the upper membrane and the lower membrane are respectively connected with the air valve membrane in a hot smelting manner and is provided with an air flow channel; the upper membrane and the lower membrane are respectively connected with an opening of the packaging bag body in a sealing manner; the upper membrane, the lower membrane and the air valve membrane are respectively provided with high-temperature-resisting anti-fusion-welding coatings; and the upper membrane and the lower membrane are connected with the air valve membrane on the printing coatings in the hot smelting manner.. The unidirectional double-face valve type inflating packaging bag has the beneficial effects that: a double-face inflating valve is adopted so that the inflating speed in the inflating packaging bag is higher and the object packaging efficiency is improved.

Description

Technical field [0001] The invention relates to the field of protection devices for article transportation, in particular to a one-way double-sided valve type inflatable packaging bag. Background technique [0002] At present, logistics is developing rapidly, and the packaging requirements for items are more stringent. The use of newspapers, rags and other measures to protect items can no longer meet the demand, and it is also easy to damage the items. At present, plastic devices with small bubbles are mostly used in the market to protect objects, but these bubble films with air are large in size and inconvenient to store and transport. There are also packaging bags that can be inflated when they are in use, but because they are inflated now, the single-sided air valve currently in use has a slow air intake speed, which affects packaging efficiency. Summary of the invention [0003] In order to solve the above problems, the present invention provides a one-way double-sided valve ...

[0002] At present, logistics is developing rapidly, and the packaging requirements for items are more stringent. The use of newspapers, rags and other measures to protect items can no longer meet the demand, and it is easy to damage the items.

At present, plastic devices with small air bubbles are often used in the market to protect objects, but these bubble films with air are large in size and inconvenient for storage and transportation

There are also packaging bags that can be re-inflated when in use, but because they are inflated now, the air valves currently used for single-sided air intake have slow air intake speed, which affects packaging efficiency
