Airtight zipper, that is a sealed zipper, is a closed zipper with waterproof, dustproof, anti-oxidation and other properties. It usually consists of two interlocking inserts with strong airtightness, which can prevent air, moisture and dust from entering the bag or container, thus keeping the contents inside clean and dry.

The application range of sealing zipper is very wide, and it can be found in aerospace, medical, military, outdoor sports and other fields. The principle, advantages and applications of sealed zippers will be introduced in detail below.

Principle

The principle of the sealing zipper is very simple, it realizes sealing by two interlocking chimeras that fit each other. The pressure between these two inserts can be adjusted by the pull of the zipper pull. When the zipper pull is slid up, the two inserts snap together securely, creating a perfect seal that keeps out air, moisture and dust.

Advantage

Airtight zippers offer several advantages, including the following:

(1) Good waterproof performance: the sealed zipper has excellent waterproof performance, which can effectively prevent moisture from penetrating into the bag or container, and protect the dryness of the internal items.

(2) Good dustproof performance: the sealed zipper can effectively prevent dust from entering the bag or container, thus keeping the items inside clean.

(3) Good anti-oxidation performance: the sealed zipper can prevent oxygen from entering the bag or container, thereby protecting the internal items from oxidation damage.

(4) Easy to use: the operation of sealing the zipper is very simple, and the sealing can be realized only by pulling the slider.

(5) Long service life: Due to the good sealing performance, the sealed zipper can effectively protect the internal items, thereby prolonging the service life.

Application

The application range of sealing zipper is very wide, the following are several typical application scenarios:

(1) Aerospace: In the field of aerospace, sealed zippers are widely used in equipment such as spacesuits, spacecraft and satellites to ensure the stable operation of internal electronic equipment and instruments.

(2) Medical: In the medical field, sealed zippers are used to make medical bags to prevent air, moisture and dust
