Bags TRIZ Cases

Micropores in the plastic film block liquid water yet allow air flow, solving the trade-off between moisture protection and ventilation.

Elastomer-modified polyolefin sealant compensates for non-parallel molecular orientation in biaxially stretched substrates to ensure even tearing.

Incorporating microparticles into multilayer films creates rough surfaces that enable effective air removal without expensive embossing steps.

Outer packing unit with buckle device secures soft vacuum bag, resolving irregular shape and stacking difficulties.

Additive manufacturing produces a monolithic filling tube with embedded channels, reducing device complexity and production costs.
