Packing bag

The spout bag is an innovative packaging form that combines flexible packaging with convenient access functions. It is made of a multi-layer composite film (such as PET, PE, aluminum foil and other materials), with a screw cover or flip-top spout structure, which has both sealing and easy operation. The contents can be directly taken out through the spout without pouring, and the bag can be easily emptied by squeezing it. It is especially suitable for the packaging of liquids (juice, beverages, soy sauce), semi-fluids (yogurt, jam, honey), pastes (hand cream, ointment) and small granular items (protein powder, meal replacement powder). Thanks to the barrier properties of the multi-layer composite materials, the spout bag can effectively resist erosion by oxygen, moisture and light, extending the shelf life of the product; and its customizability is its core advantage - the bag size can be adjusted according to needs (from mini portable packages to large-capacity packages for families), the material combination can be selected (transparent film to display the contents/aluminum foil film to enhance light protection), the type of spout can be designed (wide-mouth spout for easy pouring/narrow-mouth spout for sucking), and high-definition brand patterns, instructions for use and anti-counterfeiting logos can be customized and printed. At the same time, it supports the addition of zipper closures (for easy reuse) and easy-tear lines (to improve the convenience of bag opening) and other details, taking into account both practicality and brand communication, and is an ideal choice for lightweight, personalized and scenario-based modern packaging.
