Self-standing Composite Bags with Multi-layer Composite Structure and Double Sealing Technology for Organic Fertilizer Packaging

This composite bag is tailor-made for chemical fertilizer packaging, adopting a multi-layer composite structure of OPP outer film, optional aluminum film/foil middle layer (can be without middle layer) and PE inner film. It is strictly produced and manufactured in accordance with national standards for solid chemical fertilizer packaging, rejecting recycled materials and harmful additives. The product has excellent acid and alkali corrosion resistance and puncture resistance, which can perfectly meet the packaging needs of various chemical fertilizers such as granular fertilizer, powder fertilizer, compound fertilizer and urea. At the same time, through thickening treatment and double sealing technology, it enhances the load-bearing capacity and sealing performance of the bag body, effectively blocks moisture, locks in nutrients, avoids fertilizer caking and leakage, and comprehensively ensures the quality of chemical fertilizers during storage and transportation. With multi-specification and humanized detail design, it is suitable for various agricultural material scenarios.
