Buying Guide — Key Considerations For Choosing LDPE Bags
What size do you need? Start with a clear plan of item dimensions and required clearance. Larger items need bigger bags; smaller items benefit from compact bags to maximize visibility and minimize waste.
What thickness is right? Thicker LDPE (e.g., 1.5–2.0 mil) offers better tear resistance and durability for shipping and repeated handling. Thinner bags (0.68–1.1 mil) are cost-effective for single-use or light-duty storage.
Do you need a resealable closure? Zip bags provide repeated access and secure storage for garments, photos, and small parts. Open-end bags are cheaper and work well for bulk storage and display.
Is the bag food-safe necessary? If items will contact food, choose bags explicitly labeled for direct food contact. Some LDPE bags are food-grade safe, while others are general-purpose.
What about transparency and presentation? High-clarity LDPE helps with quick identification of contents, reducing handling time and errors in inventory or display settings.
Are there regulatory considerations? Some bags, especially those used for shipping clothing or consumer goods, may need suffocation warnings or specific labeling. Verify state or local requirements for your packaging.
