Frequently Asked Questions

Why is 12×15 considered the recommended size for t-shirts?

Most adult t-shirts in sizes S through XL fold to approximately 11×13 to 12×14 inches using a standard shirt folder or manual fold. The 12×15 bag provides a clean fit with room to insert the shirt and seal the top without bunching. For XXL and larger shirts, stepping up to the 12×18 or 14×18 size is recommended to avoid forcing the shirt and stressing the bag walls.

Can screen printed shirts go into poly bags immediately after printing?

Yes, as long as the ink is fully cured. Most plastisol and water-based inks are fully cured after passing through the dryer at the end of the press run. Bagging shirts before ink is fully cured can cause the print to block or transfer to the inside of the bag. Always confirm cure completion before bagging production runs, especially with specialty inks or thick ink deposits.

Are these bags suitable for t-shirt retail display and gifting?

Yes. The 12×15 size is widely used for folded t-shirts in retail presentation poly bags, especially for event merchandise, band tees, and promotional branded apparel sold at point-of-sale or shipped in gift wrapping configurations. For retail presentation, heat sealing the top gives a cleaner look than tape or twist ties.
