Good quality, slightly stiff at first

The material is durable and protects items well during shipping. They were a bit stiff out of the box but softened up quickly. Great value for the price.

Perfect for my boutique clothing orders

These bags are incredibly clear and make our garments look professional. The adhesive strip is strong and seals instantly without needing tape. Highly recommend for small business owners.

Fast shipping and great print quality

Ordered these with our company logo. The custom printing came out crisp and clear. The bags themselves are tear-resistant and very reliable.

Solid standard packaging

Nothing fancy, just exactly what I needed for shipping t-shirts. The seal holds well even after rough handling by couriers. Will buy again.

Excellent for holiday red envelopes

I used these to package custom red envelopes for the holidays. The transparency shows off the design beautifully, and the size 30x40 was perfect for larger gift sets.

5 FAQ

Q: What is the actual thickness in millimeters?

A: The thickness is approximately 0.025mm (25 microns), which provides a good balance between durability and flexibility for garment packaging.

Q: Is the custom printing available for orders under 500 units?

A: Custom printing typically requires a minimum order quantity of 500 units to ensure cost-effectiveness. Smaller quantities are available with standard clear finishes only.

Q: Are these bags food safe?

A: While made from non-toxic materials, these bags are intended for clothing and general merchandise packaging. We do not recommend them for direct contact with food items.

Q: Do you offer bulk discounts for 1000+ packs?

A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly or request a quote on the product page for orders exceeding 1000 packs.

Q: Can these bags be reused after opening?

A: Once the self-adhesive strip is sealed, it forms a permanent bond and cannot be reopened without damaging the bag. They are designed for single-use shipping.
