By Material

Yun Sealoong organizes custom packaging by material structure to help you balance barrier performance, print quality, and budget. This collection covers kraft paper pouches, aluminum foil bags, transparent PE and BOPP bags, metallized VMPET pouches, PA/PE vacuum structures, and recyclable or compostable material options.
Material choice drives shelf life: aluminum foil and PA/EVOH/PE provide the highest oxygen and moisture barrier for sensitive food, metallized films balance barrier and cost, transparent PE/CPP showcases the product, and kraft paper laminations deliver a natural brand look. For sustainability targets, we offer recyclable mono-PE and compostable kraft/PLA structures.
Once the material is set, everything else is custom: bag shape and size, thickness, gravure printing up to 9 colors, matte or glossy finishes, and functional features such as zippers, valves, spouts, and windows. OEM/ODM projects run from small batches to high-volume wholesale production.
Our own factory, operating since 2012, runs printing, lamination, and bag-making in purified food-grade workshops with IQC, IPQC, and FQC checkpoints. We are ISO certified, food-contact materials are FDA-compliant, products hold CE certification, and OTR/WVTR barrier values are verified through SGS testing.
MOQ is flexible by structure and printing. Browse by material below, or tell us your product’s shelf-life target, and we will suggest a structure and provide a quotation.
