Understanding the Difference between Hot and Cold Lamination

Though there has been a significant development in the office innovation space, lamination is still considered to be the best possible way to protect a printed image or document. Be it in a classroom or in an office, lamination is the most preferred alternative for protecting any important document or giving it a high-quality finish.

Lamination not only protects a printed document or page, but also provides a scratch-resistant surface to add value to it. Lamination machines are used extensively to enhance the colour of an image, adding a rigid surface to it, and protect documents against unsightly folds and creases.

While purchasing a laminator, many teachers and office managers are not sure whether they should opt of a cold laminator or hot laminator. Needless to mention, both these types have their own advantages and disadvantages. In order to make an informed purchasing decision, it is important to understand the difference between hot and cold laminators.

What is a Lamination Machine?

In simple words, laminating machines are used to add plastic coatings to images, cards, and paper documents. This is done typically by fusing plastic sheets over the surface to be laminated by applying heat or an adhesive.

While purchasing lamination machines, there are several options available to you. A thicker plastic can be used for creating a more rigid surface. On the other hand, a thinner plastic can be used for a laminate that is low cost and easier to handle.

Options are also available in terms of the machine’s size. The standard sized laminators are suitable for desktops. On the other hand, if you need to laminate banners, posters, or maps, you may need industrial-sized laminators.

Cold Laminators and Hot Laminators:

These two options relate to how the application of plastic to a document is done by the laminating machine. A cold laminator secures documents between sheets of plastic by applying pressure and an adhesive. Some users prefer these machines over hot laminators because they deliver superior quality documents without the hassle of using the heating elements.

Some noteworthy advantages of cold laminators include

  • Requires less maintenance and set-up time, inexpensive, and easier to use.
  • Solves the problem of unsightly bubbles by the application of pressure.
  • The quality and colour of the laminated documents is better in general.
  • Excellent option for adhesive decorations and decals because only one side of a graphic can be laminated.

Hot laminators, on the other hand, make use of heat to activate or melt an adhesive material. This type of lamination is generally faster, and provides more durable protection.

Some key points about hot laminators include

  • Additional laminating applications including a variety of heat settings.
  • Makes use of materials that are less expensive compared to the ones for cold lamination.
  • The high heat generated by a hot laminator can damage some materials, inks, and colours. To protect documents from the impact of heat, special plastic laminates can be used.
  • It may take some time and experience to master the skill of using a hot laminator successfully. If the users are not careful, the heating elements can cause serious danger to them.

What Is a Cold Lamination Machine and What Can It Be ...

At VariQuest, we are your source for the tools and resources you need to enhance your ability to teach students in your classroom. The goal of interactive learning is to increase the attention and retention of students, increasing their overall knowledge and comprehension in various subjects. One device that can help teachers convey important knowledge to students in the classroom is the cold lamination machine.

The Process of Cold Laminating

The process of cold laminating involves the placement of the document in between two sheets of laminating film. A pressure sensitive adhesive is applied to the film. The document to be laminated is rolled between two rollers. These rollers apply pressure to the laminating film which effectively bind it together.

The cold lamination machine is a more versatile machine than its thermal alternative. It seals all edges so you can cut close to, or even through a cold laminated paper document, keeping it impervious to water damage, and can be placed anywhere as it requires no electricity or harsh fumes. Cold lamination machines make the process of laminating easy. You simply insert a document into the feed and crank the handle.

As a teacher, you want to do everything you can to make the classroom experience the best it can be for your students. A number of laminating ideas explained below make a positive impact upon students, helping them grasp and learn material more efficiently. These include:

1. Reading Lists

Students are often assigned reading lists by teachers and those lists, if simply written on a regular piece of paper can end up ripped or crumpled in a student’s folder or backpack. However, with the use of a cold lamination machine, you can produce lists that are durable and usable for the entire school year.

2. Bulletin Board Displays

Bulletin board displays are a prominent feature in many classrooms. Whatever is displayed on these boards needs to withstand wear and tear on a daily & weekly basis. This goal can be achieved by producing laminated images, banners, and more, that motivate and instruct children in their education.

3. Multiplication Tables

Many math classes make use of multiplication tables, which are handed out to students. Producing laminated tables and charts, which can be taped to walls or desktops, can serve as a durable learning tool, students can refer to repeatedly.

4. Board Games

There are various games students can play in the classroom that enhance their learning process, including games that involve word search or math competitions, etc. When these games are played, the game pieces receive a significant amount of interaction from students, which can lead to rips and other damage to paper. Cold laminating these documents first can help ensure the pieces last a long time.

6. Interactive Classroom or Group Posters

Use cold laminated posters as class discussion pieces so when used with a dry-erase marker, you can document student participation suggestions, then wipe-clean for the next class or next year's use. This dry-erase feature is also particularly helpful when students split into groups and can move about designated stations throughout the room, completing each discussion point activity, then erasing for the next group.

5. Disinfecting Surfaces

Of course, during this time of extra sanitary precautions and disinfecting, a cold laminator is a great tool for keeping your classroom safe and clean. Cold Laminated surfaces are perfect for using antibacterial cleaning solutions and wipes so you can use teaching and learning materials over and over, while keeping them germ and virus-free.
