The key advantage of this tube is its PE lamination composite process, which forms a dense waterproof film on the surface of kraft paper, with a moisture-proof rate of 99%, effectively blocking water vapor and moisture, avoiding mold and softening deformation of packaged goods. It has an IPX5 waterproof rating, directly resisting light water spray and humid environments. The hot melt bottom seal achieves a fully sealed packaging effect, further improving moisture-proof performance. With a 20kg bearing capacity, it can stably place aquatic dried goods, horticultural fertilizers, and granular chemical raw materials. Certified to EU REACH and RoHS, it contains no harmful chemical substances, safe and environmentally friendly. It supports flexographic printing, enabling printing of moisture and waterproof warning labels to improve usage recognition.
Constructed from kraft paper with a PE lamination layer, the tube has a 2.0mm wall thickness. Optional inner diameters include 50mm, 80mm, 100mm, 150mm, 200mm, 300mm, and 400mm, with standard lengths ranging from 200mm to 1800mm. Individual tube weights range from 50g to 500g, depending on dimensions. The hot melt bottom seal is applied via automated machinery for consistent sealing. Printing supports flexographic printing, with custom moisture and waterproof warning labels available. It has an IPX5 waterproof rating and meets international packaging moisture-proof standards, suitable for direct contact with non-corrosive chemical raw materials and aquatic dried goods.
Primary applications include the aquatic product industry for packaging aquatic dried goods and pickled aquatic products; the horticultural agricultural materials industry for packaging fertilizers, seeds, and horticultural tools; and the chemical industry for packaging non-corrosive granular chemical raw materials. It serves aquatic product processing plants, agricultural material stores, and chemical warehouses with humid or high-humidity environments, helping goods avoid moisture damage and improving storage and transportation safety. Ideal for large-scale bulk moisture-proof packaging procurement.
