Information

Foil aluminum bags have become a common product in our lives, especially in hospitals and other places. Foil aluminum bags also have different packaging. How can we detect its quality problems?

foil aluminum bags

1. Appearance: Take this product, bright under natural light, and face the vision. There should be no perforation, foreign matter, adhesion, separation of the composite layer, obvious damage, air bubbles, wrinkles, dirt; the heat-sealed part of the composite bag should be smooth and unsealed, and easy to open when opened.

2. Size: Use a qualified 5m steel tape measure to measure the width and height of the sample, and then measure the single-layer thickness of the sample by a qualified digital electronic micrometer (specification: 0 ~ 25mm). The measured data shall be within a width of 110± 2mm, a height of 150± 5mm, and a single layer thickness of 0.08 + 0.008mm.

How can I measure the tightness of an foil aluminum bags without using an instrument?

1. The sealed bag can be immersed in water and squeezed with the palm of your hand to see if there are any air bubbles!

2. Don't seal it with a steel ruler, seal the edge with the round head, see if the edge is sealed well, then cover your eyes with a bag, and look at the light to see if there is light transmission. It should be explained that light transmission is not necessarily difficult to seal: the aluminum foil has trachoma that meets the standard, and the light transmittance; the edge sealing has time, and the bag time pressure is large. Flexible packaging inspection instruments such as aluminum foil shearing machine, heat sealing machine, sealing machine, etc. are available for reference.

The above is a partial introduction to the detection method of foil aluminum bags, I hope it can help you.
