Great size for hoodies

The 30x40 size fits folded hoodies and sweatshirts perfectly with a little room to spare. Easy to peel and stick. One bag arrived slightly crinkled but the rest were flawless.

Excellent for mask packaging

We use these to package cloth face masks. They look very sanitary and professional. The adhesive holds well even in humid conditions. Highly recommended for small businesses.

Reliable and durable

Ordered these for shipping orders. None of the strips failed during transit. They keep the clothes dry and clean. Will definitely reorder when I run out.

Crystal clear presentation

I use these for my handmade clothing line. The transparency is excellent, making the products look professional. The self-seal mechanism is very convenient and saves time.

Good quality, slightly thin

Great value for the price. They work well for socks and masks. I wish they were just a tiny bit thicker for heavier items, but for standard clothing, they are perfect.

Perfect for my online boutique

These bags are exactly what I needed for packaging shirts and hoodies. The adhesive strip is strong and seals tightly every time. Very clear so customers can see the product immediately.

5 FAQ

Q: Is the 30x40 measurement internal or external?

A: The dimensions 30cm x 40cm refer to the external size of the bag. The internal usable space will be slightly less due to the seal area.

Q: What is the actual thickness of the plastic?

A: The bags are approximately 25 microns thick, which provides a good balance between durability and flexibility for garment packaging.

Q: Are these bags food safe?

A: No, these OPP bags are designed specifically for non-food items like clothing and accessories. We do not recommend using them for food storage.

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

A: Yes, you can write on the surface of these bags with permanent markers or ballpoint pens without the ink smudging easily.

Q: Do the adhesive strips lose stickiness over time if unused?

A: If stored in a cool, dry place away from direct sunlight, the adhesive strips maintain their effectiveness for up to 12 months.
