Strong adhesive seal

The peel-and-seal mechanism works flawlessly. I've had issues with other brands where the strip doesn't stick, but these hold up well during shipping.

Perfect for my boutique

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

Crystal clear finish

I use these for handmade masks and they look very professional. The transparency is excellent and there are no cloudy spots. Highly recommend for small businesses.

Good quality, fast shipping

Solid plastic bags that don't tear easily. The 30x40 size is great for hoodies. Only giving 4 stars because I wish they came in larger bulk quantities.

Great value for money

For the price, you get a lot of high-quality bags. They are crisp and make my products look premium. Just be careful not to overfill them as they are not stretchy.

Standard size fits perfectly

The 30*40 dimension is ideal for folded t-shirts and light jackets. No wrinkles in the plastic upon arrival. Will definitely order again.

5 FAQ

Q: Is the adhesive strip reusable?

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

Q: Can I print my logo on these if I buy in bulk?

A: Yes, we offer custom printing services for large orders. Please contact our sales team with your logo file and quantity requirements for a quote.

Q: Are these bags food safe?

A: While made from non-toxic OPP material, these bags are specifically designed and tested for clothing and dry goods packaging, not for direct food contact. We recommend using food-grade certified bags for edible items.

Q: What is the actual thickness of the plastic?

A: The bags have a thickness of approximately 25 microns, which provides a good balance between durability and flexibility for retail packaging.

Q: Do these come with hang holes?

A: No, this specific model (30*40 standard) does not include pre-punched hang holes. However, they can be easily punched manually if needed for display racks.
