FAQS
Polyethylene (PE) bags are generally more flexible and cost-effective, making them ideal for general packaging. Polypropylene (PP) bags, however, offer higher tensile strength, temperature resistance, and clarity. PP is preferred for applications requiring greater durability or when visual appeal is important, such as packaging for retail products. Both materials are recyclable, though the specific recycling processes can vary.
Bag thickness is measured in mils (thousandths of an inch). The ideal thickness depends on the product's weight, shape, and potential for punctures. Lighter products typically require thinner bags (0.5-1 mil), while heavier or sharper items need thicker bags (2-6 mil or more). Consider testing different thicknesses to find the optimal balance between protection and cost.
