We manufacture a wide range of custom flexible packaging bags, including three side sealed bags, Mylar bags, child resistant bags, Doypacks, standing pouches, and block bottom bags. Different bag structures are available depending on the product, filling method, barrier requirements, shelf display, and storage conditions.

A Doypack is a type of stand-up pouch with a specially shaped bottom gusset that allows the pouch to stand upright after filling. The term standing pouch or stand-up pouch is broader and can refer to different pouch structures designed to stand on shelves. Both types can be customized with features such as: 

Zippers

Tear notches

Hang holes

Spouts

Degassing valves

Transparent windows

Matte or glossy finishes

A three side sealed bag is a flat pouch sealed on three sides, leaving one side open for filling.

After the product is filled, the remaining side can be heat sealed.

Three side sealed bags are commonly used for:

Snacks

Food ingredients

Coffee

Tea

Powder

Supplements

Pet treats

Cosmetics

Electronic accessories

They are suitable for both small-volume packaging and high-speed production.

Mylar bags are commonly used for products that require good protection against moisture, oxygen, light, and external contamination.

The actual barrier performance depends on the complete laminated material structure rather than the outer film alone.

A child resistant bag is designed with a special closure system that makes the package more difficult for young children to open while remaining usable by adults.

Child resistant pouches are commonly used for products that require additional packaging safety.

Different child resistant zipper structures and pouch styles are available depending on the target market and packaging requirements.

Sizes

Materials

Thicknesses

Printing designs

Zipper structures

Surface finishes

Barrier properties

Hang holes

Please tell us your product type and target market so that we can recommend a suitable packaging structure.
