This liquid packaging pouch is built for viscous sauce products, using a stand-up spouted bag design with widened four-side or three-side heat sealing that withstands stacking and transport without leaking. The large-diameter plastic spout keeps thick fills flowing smoothly, which suits sesame paste, chili oil and similar low-flow products. A screw cap or inner plug can be added so the pouch stays resealable after opening, making it convenient for end users to dispense and store the contents.
Pouches are typically laminated as PET/PA/PE or PET/AL/PA/PE, with a food-grade sealing layer inside; film thickness and barrier structure can be adjusted for oil resistance, acid resistance or light blocking. Surfaces accept 1-8 colour gravure printing, giving stable registration and rich colour for brand artwork, ingredient text, barcodes and usage notes. Fills range from 100ml to 6L, with 1L, 3L, 5L and 6L most common, and matching roll film in the same material can be supplied for your own filling line.
These bags serve condiments, hotpot bases, edible oils, pickled vegetables, jams, juices and household liquids, from retail packs to catering and industrial bulk sizes. Customisation starts with your sample or drawing: confirm bag style, dimensions, spout specification and print artwork, then approve a proof before mass production. Our factory in Dongguan, Guangdong runs a Class 10000 clean workshop covering film blowing, printing, lamination and bag making, with an MOQ of 10,000 pcs.
