Common Questions
Q: How many folded shirts can I fit in a 12x20 bag?
A: A standard folded adult t-shirt fits perfectly with room for tissue paper or a thank-you card. You can fit 2-3 thinner items like tank tops or scarves in a single bag.
Q: What's the difference between 4 mil and thinner poly bags?
A: At 4 mil, these bags are considered heavy-duty — about twice as thick as standard 2 mil bags. They resist tearing, provide better puncture protection, and feel more premium to customers. Ideal when shipping items with buttons, zippers, or anything that might poke through thinner material.
Q: Can I seal these bags without a heat sealer?
A: Yes! While heat sealing gives the cleanest look, you can also fold and tape, use a sticker seal, or tie with ribbon. Many sellers use decorative washi tape for a boutique touch.
