To pack heavy winter coats without tearing, choose frosted zipper bags with a thickness of at least 70 to 100 microns (approximately 2.8 to 4 mils) per side. Heavy-duty frosted zipper bags within this thickness range provide the necessary tensile strength, puncture resistance, and sealing durability to withstand the weight and bulk of heavy outerwear during storage and logistics.
Frosted zipper bags made from low-density polymers rely on material thickness to distribute mechanical stress. When packing compressed winter coats, internal air pressure and the bulk of the fabric exert constant outward force on the side seams and the zipper closure. Selecting a sub-standard thickness leads to seam splitting and zipper failure during handling.
Manufactured under strict ISO 9001 Quality Management and BSCI standards, our frosted zipper bags undergo rigorous spot checks to ensure consistent thickness and tear resistance. For instance, in large-scale e-commerce logistics, such as our supply of over 65 million packaging units to Russian platform Ozon and over 6 million packaging pieces to Matalon in Greece, durable garment packaging is vital to minimize parcel damage during transit.
Heavy-duty frosted zipper bags prevent tearing and maintain structural integrity under high pressure.
