Perfect for my online boutique

These bags are incredibly clear and make my clothing items look professional. The adhesive strip is strong and seals tightly every time. Highly recommend for small business owners.

Great value for the price

Bought these to organize my paperwork and old photos. They fit A4 sheets perfectly with a little room to spare. One bag had a slight defect in the seal, but the rest were perfect.

Crystal clear quality

I use these for packaging handmade jewelry. The transparency allows customers to see the product immediately without opening the package. Very durable material.

Excellent clarity

No cloudiness at all. These look much more premium than the generic ones I bought at a local office supply store. Will definitely reorder.

Good for shipping books

Protects my used books from rain during delivery. Wish they came in a slightly larger size option for hardcovers, but the A4 size works for most paperbacks.

Sticky strip works well

Sometimes self-seal bags lose their stickiness, but these have been great even after sitting in storage for a few months. Easy to peel and very secure.

5 FAQ

Q: Are these bags food safe?

A: While made from non-toxic OPP material, these bags are not certified for direct food contact or long-term food storage. We recommend using them for dry goods like clothing, books, or stationery only.

Q: Is the adhesive strip reusable?

A: The self-adhesive strip is designed for a single strong seal. Once opened, the adhesive may lose some effectiveness, so it is best used for one-time sealing or shipping purposes.

Q: Do you offer bulk discounts for orders over 50 packs?

A: Yes, we offer tiered pricing for bulk purchases. Please contact our sales team through the 'Contact Seller' button for a custom quote on large volume orders.

Q: What is the exact width and length of the A4 size?

A: The internal dimensions are approximately 220mm x 310mm, which provides ample space for standard A4 paper (210mm x 297mm) to slide in easily without bending.

Q: Can I write on these bags with a permanent marker?

A: Yes, the smooth surface of the OPP material accepts permanent markers very well, making it easy to label contents or write shipping information directly on the bag.
