Good but adhesive varies
Most of the bags work perfectly, but I found about 5 in the pack where the adhesive strip wasn't sticky enough. The rest were fine though.

Perfect for my online boutique
These bags are exactly what I needed for shipping clothes. They are crystal clear, so customers can see the product immediately, and the adhesive strip is very strong. No issues with packages opening during transit.

Great quality, slightly stiff
The material feels durable and professional. The only reason I didn't give 5 stars is that the plastic is a bit stiff, making it slightly harder to insert bulky items, but overall a great purchase.

Excellent value for money
You get a lot of bags for the price. The clarity is impressive, and they don't have that cloudy look cheaper bags often have. Will definitely reorder.

Ideal size for textbooks
I bought these to protect my children's textbooks during the school year. The 30x40 size fits most standard hardcovers perfectly. The seal stays shut firmly.

Professional packaging solution
Using these for my Etsy shop has elevated my brand image. They look clean and professional. The self-sealing feature saves me so much time compared to taping boxes.
Q: What is the actual thickness of the plastic?
A: The bags are manufactured with a thickness of approximately 25 microns, providing a balance between durability and flexibility.
Q: Can I write on these bags with a marker?
A: Yes, you can write on the surface of these bags using a permanent marker. The ink dries quickly and does not smudge easily.
Q: Do these come with a perforation for easy opening by the recipient?
A: No, these specific bags do not feature a tear-off perforation strip. They must be opened by peeling the sealed edge or cutting.
Q: Will a standard A4 document fit inside?
A: Yes, an A4 sheet (21 x 29.7 cm) fits comfortably inside the 30 x 40 cm bag with plenty of room to spare.
Q: Are these bags suitable for food storage?
A: No, these OPP bags are intended for non-food items such as clothing, books, and documents. They are not certified food-safe.
