Description

Sealing performance test bag for packaging bag

Technical Field

A sealing performance test bag for a packaging bag belongs to the technical field of paper bag sealing test.

Background

The packaging bag is usually composed of a dialysis material and a transparent film, or a transparent film and a transparent film. The sealing of the sealing edge formed by the dialysis material and the transparent film can, under certain conditions, present microscopic channels which are not visually perceptible. Such passageways can compromise the sealing properties of the package and bacteria in the environment can enter the package through the passageways and cause damage to the sterile packaging of the sterilized instrument.

The preparation and use of the test solution are limited, for example, the preparation process of the dyeing solution requires the use of a quantitative tool and special equipment, and if the dyeing solution is accidentally splashed to the ground or clothes, dyeing is caused. The test methods in the prior art are mainly divided into two types, specifically as follows: (1) an injection method: and (3) sucking a proper amount of test solution by using a dropping bottle, and dropping for measurement, wherein only 1 edge sealing performance is tested by the method for 1 time. The sealed bag is hot-sealed at least 3 sides, so the injection method can only test 1 side 1 time, so the efficiency is slow. (2) The drip method comprises the following steps: sealing the end of the paper-plastic bag 4 to be tested, breaking a small hole on the paper surface by using a breaking tool (a knife), sucking a proper amount of test liquid by using a syringe or an eye dropper, dropping the test liquid from the position of the small hole, rotating the test side for four sides, and testing the sealing leakage of the four sides. However, the instillation method requires the use of a syringe with a needle, so that such an operation may cause the needle to pierce the skin.

The tools and the test liquid used in the injection method and the drip method need to be configured or need to be contained in special measuring cup tools, and the test process is easy to drip and splash to contaminate test beds, clothes and the like. Thus, the art lacks a clean and convenient product format.
