These are embossed texture vacuum pouches for 5kg pickled vegetables, built on a multi-layer laminated structure. Common material combinations include PET/AL/PE, PET/NY/PE, PET/VMPET/PE, PET/PE, PA/PE, PET/AL/NY/PE, kraft paper/PE and PET/VMPET/NY/PE, with a thickness of 15–25 silk (multi-layer lamination); the structure can be selected according to the oil content, acidity and packaging requirements of the pickled vegetables.
The embossed texture is the key difference between this product and standard smooth-surface vacuum pouches of the same size and application: the pouch surface is embossed with an even raised pattern, and the channels between the raised areas act as air-evacuation paths during vacuuming, helping to reduce residual air inside the pouch and air trapped in folds at the seal, and working with the evacuation method of external-suction vacuum packaging equipment. The texture also improves the stiffness and hand feel of the pouch surface, making 5kg filled bags easier to handle and stack.
Production follows the process flow of gravure printing → lamination → slitting → bag making → heat sealing. Printing supports 1–8 colour gravure printing for brand artwork and product information, and bag making and heat sealing are carried out in a Class 10,000 clean workshop. Food-grade materials are used, and material certificates can be provided upon customer request.
For customisation, the factory supports sampling from customer samples or artwork, and customises pouch dimensions and artwork to customer requirements, with a minimum order quantity of 10,000 pieces, produced in Dongguan, Guangdong. The pouches are suitable for 5kg vacuum packaging of pickled vegetables, zha cai, suan cai and similar preserved foods, with bag dimensions adjustable to fill weight and seal width.
