Frequently Asked Questions

What size cookies fit in a 12cm self-sealing bag?

A 12cm square bag comfortably fits round cookies up to approximately 10–11cm in diameter, or a small stack of mini cookies and chocolates. For larger decorated cookies (12cm+), consider our 15cm or 18cm self-sealing bags, also available at Baking Pleasures.

Do these bags need a heat sealer?

No — these bags have a self-sealing adhesive strip. Simply press the strip down firmly to close the bag. No heat sealer, twist tie or ribbon is required, making packaging fast and efficient for bulk orders.
