gusseted bags United Kingdom

...-sealed bags are hermetically sealed, ensuring that your products are tamper-proof, airtight, waterproof, and hygienically closed. Often, you will have a bag or pre-cut pouch that will contain identical monolayers. In other words, only "single-layer" materials. Like simple plastic bags. Other containers, such as aluminum foil bags or gusseted bags, may have multiple layers that need to be sealed at once.
