For ice crystal powder, freezer packs and cold-chain cooler inserts, these aluminum foil / metallized pouches can be specified as three-side seal, four-side seal or stand-up zipper bags. The pouch body stays upright and resists collapsing after filling with ice gel powder or super absorbent resin. Opening choices include flat top, zipper, spout and one-way degassing valve. Wide heat-sealed edges and rounded corners help reduce seal cracking during drop handling and low-temperature use, so the packs fit neatly inside picnic bags and insulated takeaway boxes.
The laminate typically combines aluminum foil or metallized PET with a PE or CPP sealant layer. Film grammage and layer count can be adjusted to meet moisture-barrier, light-blocking and cold-resistance requirements. Printing uses 1-8 color gravure, covering full-coverage backgrounds, spot colors and matte or gloss finishes. Pouch style, dimensions, volume, thickness and seal width are customized to your drawing; standard volumes range from 100ml to 5L, and matching roll film in the same structure can also be supplied.
Common uses include frozen foods, ice crystal powder, fresh cold chain, takeaway thermal insulation and outdoor picnics, along with powders and granules that need moisture and light protection. The customization path is straightforward: discuss requirements, sample from your sample or artwork, confirm the sample pouch, then bulk production and shipment. Our factory is in Dongguan, Guangdong, operating a Class 10000 cleanroom. We support customization from samples or drawings, with an MOQ of 10,000 pcs and production scheduled according to the confirmed timeline.
