Paper laminated bags, also known as block bottom bags or square bottom bags, are a type of packaging solution widely used in various industries for storing and carrying a wide range of products. These bags are made from a combination of high-quality paper and laminated materials, such as plastic or aluminum, which enhances their durability and strength while maintaining their eco-friendliness. Construction: The bags are typically made of multiple layers, including an outer layer of paper and an inner layer of laminated material. The laminated layer provides additional protection against moisture, grease, and other external elements. Square/Block Bottom: The distinctive feature of these bags is their square or block-shaped bottom. This design allows the bag to stand upright and maintain its shape, making it easier to fill and stack. Reinforced Handles: Paper laminated bags often have reinforced handles for comfortable carrying, ensuring they can withstand the weight of the contents.
