Common Questions
Q: What's the difference between polypropylene and polyethylene bags?
A: Polypropylene (PP) offers better clarity and a crisper feel than polyethylene (PE). PP bags are preferred when product visibility and presentation matter—ideal for jewelry, collectibles, and retail display. PE bags are softer and more flexible, better for protective packaging.
Q: What fits in a 3x4 bag?
A: This size accommodates items up to approximately 2.5 x 3.5 inches with room for easy insertion. Common uses include single earring pairs, small pendants, 5-10 loose beads, business card inserts, USB drives, or sample-size products.
Q: Can these bags be heat sealed?
A: Yes, polypropylene seals easily with a standard heat sealer or impulse sealer. Set temperature to 250-300°F for clean, secure seals.
