subject: Various Laminators For Different Uses [print this page] Lamination involves the application of a thin sheet of plastic on an object. When this procedure is applied to documents identification cards, menus, printed matter, photographs, etc they become tear and wrinkle proof, smudge and fingerprint resistant, and waterproof. And when the applicable pouch is applied, the color and contrast are enhanced as well.
The Lamination Process
For the majority of printed documents, lamination involves a pouch and a laminator. The former is two sheets of plastic that are attached on one edge. These may vary in terms of dimensions and thickness depending on the purpose. At the same time, there are matte and gloss finishes available. Laminators are used to provide heat and pressure for the plastic sheets to adhere and encapsulate the document. For this particular procedure, a pouch laminator is used. When larger items are laminated, heated roll laminating machines are utilized.
In instances wherein the material to be laminated is heat sensitive, e.g. photographs, a cold laminator is called for. This employs pressure and adhesive. And since heat is not applied, the integrity of the documents is not affected. However, the output is not as durable as laminates produced by hot pouch or roll laminating machines.
Choosing a Laminator
The choice of laminator depends on several factors. Among these are:
1. The item to be laminated: If you have heat sensitive documents, using a cold laminator with the appropriate cold laminating pouch is your only option. Other types of laminators that employ heat are likely to ruin the document.
2. The size of the documents: This will dictate the particular laminator to acquire. Most pouch laminating machines can accommodate documents up to size A3. If you will be working on identification cards and documents using letter size paper, then these machines are sufficient. Check the specifications of the particular model you have in mind to determine if it can accommodate your intended document size.
3. The thickness of the plastic laminate that you plan to use: This will depend on how the document will be utilized. Menus that will be subjected to heavy use will require a thicker laminate such as a 250 micron pouch. You have to make sure that your laminator of choice can handle this thickness.
4. Frequency of use: There are laminators that are designed for heavy-duty use. These are the ones with 4 rollers for robust construction and faster laminating speed. This type is highly recommended for commercial operation. Occasional to moderate use only require 2-roller machines. Although these are not as strong as the 4-roller design and they do not possess the same laminating speed, they will adequately serve the purpose. Also, their price is significantly lower.
5. The price: Affordability is always an issue when purchasing any item, and these machines are no different.
Laminating machines can be sourced online for optimum buying convenience. However, is best to check the detailed specifications and reviews before making a final decision. Also, dealing with a reputable supplier will ensure fewer problems during and after the purchase.
