Fast shipping and great quality

Arrived earlier than expected. The 5-micron bags are surprisingly tough for their thinness. Perfect for our stationery shop. Will definitely reorder when we run out.

Ideal for Red Envelope season

Bought these specifically for packaging red envelopes for gifts. They fit perfectly and the double-sided tape makes sealing very quick and neat. Highly recommend for holiday preparations.

Perfect for my boutique clothing line

These bags are incredibly clear and make my garments look professional. The adhesive strip is strong and seals tightly every time. I ordered the 8-micron thickness and it feels durable without being too stiff.

Good bags, adhesive could be stronger

The bags themselves are nice and clear, but I found the adhesive strip sometimes loses its stickiness if you need to reposition it. Once sealed though, it holds well. Good for light-duty use.

Sturdy and crystal clear

I tried the 10-micron version and it is very robust. Great for heavier items like thick cardstock or multiple clothing layers. No cloudiness at all, customers can see the product clearly.

Great value, slight sizing variance

Overall excellent product for the price. I use them for packaging greeting cards. A few bags were slightly off in width by a millimeter, but nothing that affected usability. The transparency is top-notch.

5 FAQ

Q: Is the adhesive strip reusable?

A: The double-sided tape is designed for a permanent seal. While you can carefully peel it open before fully pressing it down, once firmly sealed, removing it usually damages the bag or reduces the adhesive effectiveness.

Q: Do the bags have a hole for hanging hooks?

A: No, this specific model (30*40 cm) does not come with a pre-punched hang hole. It is designed as a flat seal bag. If you need hang holes, please check our 'Header Bag' category.

Q: Can I print my logo directly on these bags?

A: Yes, OPP material is generally suitable for flexographic or rotogravure printing. However, these come blank. For custom printing, you would need to contact us for a bulk custom order or apply labels externally.

Q: Are these bags food safe?

A: While made from polypropylene, these bags are intended for non-food items like clothing, cards, and gifts. We do not recommend using them for direct food contact unless specifically certified for food grade, which this standard listing is not.

Q: What is the difference between 5, 8, and 10 micron?

A: The micron measurement refers to thickness. 5 micron is lightweight and best for soft goods like scarves. 8 micron is our standard for t-shirts and general apparel. 10 micron is the thickest, offering maximum protection for heavier or sharper items.
