When it comes to laminating, the terms "seal" and "self-adhesive" are often used interchangeably, but they actually correspond to two different types of pouches with specific characteristics. In this article, we will discuss both self-adhesive and self-adhesive pouches to help you understand the similarities and differences between the two pouch styles.

Self-adhesive laminating films
Also called self-adhesive, self-laminating, or cold-laminating pouches, self-adhesive laminating pouches are made from pressure-sensitive laminating film and do not require heat to seal the document. As with laminating with pressure-sensitive roll laminating film, cold pouches will not damage heat-sensitive documents (e.g. digitally printed materials). To use self-adhesive pouch film, simply remove the backing that lines the adhesive side of the pouch, insert your document and press the layers firmly together to create a seal. This type of bag is significantly more expensive than traditional thermal bags. So if you are looking to laminate large quantities of documents, consider purchasing a pouch laminator to take advantage of the lower prices of thermal pouches. If you are laminating just a few documents, are laminating as part of a one-off project, or are laminating on-site (without access to electricity), self-laminating pouches may be the ideal choice for you.
Laminating pouches with sticky backing
Glue pouches are similar to traditional thermal overlaminate film in that they require heat to create a seal around the document. The unique feature of sticky laminating pouches is that they have an adhesive backing that allows the laminated document to be stuck onto a folder, bound presentation, sign or any other smooth surface. After placing the document in the pocket and running it through your laminator at the right temperature, simply peel off the release liner on the back of the film to reveal the adhesive and attach as desired. Although the cost of the additional adhesive backing is reflected in a higher retail price compared to standard thermal pouches, sticky backed laminating pouches are much more cost effective than self-adhesive pouches.
In retrospect
Although the terms self-adhesive and self-adhesive may sound similar, the products they refer to are actually very different. Self-adhesive (cold) pouches use pressure-sensitive adhesive to encapsulate documents without using a thermal laminator. Because they don't require a thermal laminator, these pouches are a great option for small laminating projects or for laminating heat-sensitive documents. They require more manual labor and cost significantly more than thermally laminated pouches. So if you are planning to laminate a large amount of documents, you should definitely consider buying a machine that allows you to use thermal laminating pouches. Adhesive pouches are thermal laminating sleeves with a self-adhesive backing, allowing the user to attach them to any smooth surface. Like any other thermally laminated pouch, they must be passed through a laminator to achieve a seal. The additional adhesive backing is slightly more expensive compared to standard thermal bags, but they are still significantly cheaper than self-adhesive bags.
