Why Choose 3 Mil Thickness
Standard 2 mil poly bags work for lightweight items, but heavy-duty applications demand more. The 3 mil thickness provides approximately 50% more material than standard bags, delivering:
- Puncture Resistance: Sharp edges and pointed items won't poke through
- Tear Strength: Heavier items stay secure during handling and shipping
- Professional Appearance: Thicker material looks and feels more substantial
- Reusability: Bags hold up to repeated opening and handling
Key Features
- Heat Sealable: Create tamper-evident sealed packages with any impulse sealer
- Crystal Clear: Contents remain visible for inventory management and identification
- Lay-Flat Design: Stores efficiently in drawers, bins, and organizer systems
- Virgin LDPE: Clean, consistent material with no recycled content odors
Size Reference
The 4x7 inch size accommodates items up to approximately 3.5" x 6.5" with room for sealing. This makes it ideal for small parts, individual hardware packs, and compact accessories that need extra protection.
