Inner laminating woven bag production line
The primary functions of woven bags with an inner lining (inner-lined bags) are to provide waterproofing, moisture resistance, and protection against powder leakage and seepage, as well as to prevent slipping during stacking, thereby indirectly reducing the risk of items falling. Suitable for the packaging, storage, and transportation of bulk materials that require high levels of sealing integrity and cleanliness, it is widely used in industries such as agriculture, chemicals, building materials, food, and animal feed.
Production Process for Inner Lining Woven Bags:
Step 1: Use this equipment to co-extrude HDPE or LDPE with EVA material in a two-layer process to produce a roll of inner film. https://berlanmachinery.com/en-id/produk/d7154883-a155-4c8c-8a78-8b03ea24b608
Step 2: Place the blown-film liner roll into the circular knitting machine and knit tubular fabric using the machine. https://berlanmachinery.com/en-id/produk/19774b21-54b3-49b0-9576-fcca5b1cf01b
Step 3: Liner Laminating (Critical): Using a liner laminating machine, the woven fabric and liner are fed through the machine simultaneously. After being heat-pressed and bonded in a heating oven and cooled to set the shape, the material is wound into a laminated roll. https://berlanmachinery.com/en-id/produk/aeadfde5-8491-4708-9e6e-c96b44490043
Step 4: Bag Forming: The laminated tubular fabric passes through a bag-making machine, where it undergoes cutting, folding, bottom sewing/heat sealing, top heat sealing/curl forming, and hot cutting, resulting in finished bags.
