12 x 18 2 Mil Clear Poly Bags 500 Count - Heavy Duty Packaging

Our review of these 12 x 18 clear poly bags finds them best suited to small businesses, crafters, and anyone needing simple, archival-safe storage in bulk. The single biggest reason to buy is straightforward: you get 500 heavy duty, crystal clear, heat-sealable bags that protect and display items without adhesive flaps or printed patterns. For sellers who need consistent, glossy presentation and durable protection for items like notebooks, purses, and art supplies, these open-ended bags are a practical, cost-effective choice.

Key Features

• 500 Count Bulk Pack: A large bundle keeps a steady supply on hand so packing and shipping runs without frequent reordering.
• 12 x 18 Size: A versatile dimension that comfortably fits mid-size items such as binders, handbags and flat artwork for mailing or storage.
• 2 Mil Thickness: Manufactured from virgin LDPE for a thicker feel that resists tearing and holds shape under normal handling.
• Crystal Clear: A glossy, transparent finish provides clean, professional presentation and makes contents instantly visible.
• Heat Sealable Open End: The flat open-ended design can be sealed with an impulse sealer or closed with tape or ties for secure shipping.
• 100% Acid-Free: Archival-safe material suitable for storing artwork, photographs, and delicate keepsakes over time.

Who It's For

These bags are ideal for small retailers, makers, and schools that need a reliable, clear packaging option in bulk. Because they are heat-sealable and acid-free, they suit sellers who want a neat presentation for products like planners, fabric swatches, or assembled art kits.

Users who need resealable protection or padding should look elsewhere; these are open-ended, non-printed bags intended for containment and display rather than cushioning or tamper-evident closure.

Pros & Cons

Pros

• Consistent bulk supply reduces frequent purchasing and streamlines packing workflows.
• The 2 mil virgin LDPE construction offers dependable durability and resistance to punctures.
• Crystal clear gloss enhances product presentation for retail and shipping photos.
• Acid-free composition makes these bags suitable for long-term storage of paper and artwork.

Cons

• Open-end design means an external sealer or tape is required for permanent closure, which adds a step to packing.
• Thickness is generally well regarded but some users may prefer a heavier gauge for very sharp or heavy items.
