Technology and Product

We will select film material for tight-sealing bag according to your storage purpose. According to the purposes, such as moisture exclusion, antirust and deodorization and also required protection level, we can make a proposal of best suited film from our variations.
Also, we can get better effect using together with drying agent.

From small size, such as storage case of eye-drop bottle, to bigger size, such as sealing/protection bag for larger equipment, we can respond to various sizes.
We can arrange the bag shape or add bottom gusset for stereoscopic storage too.

For tight-sealing bag, air-tightness of zipper portion is very important. We are mainly using Double-Zipper which is our own designed with high air-tightness.
Also for easy opening, we designed the bump at the back and front.

Slider part is the part to shut-off tight-sealing zipper.
Tight-sealing zipper can't maintain the compression as the air is coming-in if there is unsealed small portion even a few mm. Also structure of tight-sealing zipper is much heavier comparing with general zipper, so it can't be closed lightly. So, the slider is very important part for the tight-sealing zipper.
We develop exclusive use slider parts for each shape of zipper by ourselves to keep better air-tightness of compression bags.

Ishizaki-Shizai applies waterproof/tight-sealing technologies to produce various products other than those products. We may ask customer's needs or request and we can make a proposal matching to your application and using environment. Please consult with us for custom-made order of other compression bags too. We also can supply your own printing, such as logo mark.
