What Should I Know About Laminating?
Laminating is an essential way to preserve, protect, and enhance documents, photos, and various projects. Whether you're a teacher, business professional, or craft enthusiast, understanding the different types of lamination, film thickness, and finishes can significantly improve the quality of your laminated work. Let’s go through everything you need to know about laminating, from selecting a laminator to choosing your laminating film. So you become a laminating master.
Laminator Type: Thermal vs. Pressure Sensitive
Laminators can apply laminate in two different ways, with heat or with pressure. Therefore, laminate comes in two main types: thermal ("hot") and pressure-sensitive ("cold"). Most machines will specialize in one type of film but some can achieve both hot and cold lamination.
Thermal Laminate
Thermal laminate, or "hot" laminate, features a heat-activated adhesive that bonds to your documents when it passes through the hot rollers of a laminator.
- Application: Requires a laminating machine to apply, reaching temperatures of 300°F or higher. Requires machine heat up time before it is able to be used.
- Cost: Typically the most affordable option over time. Thermal machines often cost more up front but thermal laminate is much cheaper than the pressure sensitive options.
- Uses: Ideal for high-volume tasks like posters, signs, and educational materials.
- Limitations: Not suitable for heat-sensitive materials like photo prints with water-based inks or archival pieces.
Pressure-Sensitive Laminate
Pressure-sensitive laminate, or "cold" laminate, uses an adhesive that bonds at room temperature using just pressure.
- Application: Does not require a laminating machine, though cold laminators can simplify the process. These machines need no warmup time and some don’t even need electricity.
- Cost: Initially low startup cost, but the film itself is more expensive long-term.
- Uses: Excellent for laminating photos, artwork, and other heat-sensitive materials.
- Limitations: Less popular than thermal laminate, leading to higher prices and fewer options.
Laminate Type: Roll vs. Pouch
Laminating film can come in two different forms. Roll laminate is a long flat sheet of film that has been wound onto a core. Pouch laminate it a sheet of film that has been folded in half. The type that you will use is determined by which type of machine you have.
Roll Laminate
Roll laminate is typically used for high-volume or large-format laminating tasks. It involves feeding a continuous roll of laminating film through a laminator, making it ideal for extensive projects.
- Application: Requires a roll laminator. One roll is threaded through the top and one through the bottom. Simply run documents through the machine to apply lamination.
- Efficiency: Excellent for high-volume laminating, reducing the need to reload film frequently.
- Versatility: Suitable for posters, banners, and large educational materials.
- Cost: More cost-effective for bulk laminating compared to pouches, especially for large items.
Pouch Laminate
Pouch laminate is designed for individual items, making it perfect for smaller, more simple laminating tasks. It involves placing the document inside a pre-sized pouch, which is then fed through the laminator.
- Application: Usually requires a pouch laminator. Your document is placed in the pouch and then run through the laminator crease-side first.
- Convenience: Pouches come in various standard sizes, eliminating the need for trimming. Simple setup with minimal to no learning curve so you can immediately start laminating.
- Uses: Ideal for ID cards, photos, certificates, and standard sized documents.
- Cost: Slightly higher per item compared to roll laminating but offers precision and ease of use.
Laminator Size
What you are able to accomplish with your laminator will be limited by its size, or maximum width it is able to accept.
3” – 9” Wide Laminators
Small laminators are ideal for everyday office and home use. These laminators are compact, portable, and easy to store. They are perfect for:
- ID Cards and Badges
- Photos
- Letter Size Documents
12” – 30” Wide Laminators
Medium & large laminators are suitable for a broader range of tasks. These laminators are versatile and can be used in schools, offices, and craft rooms. They are ideal for:
- Legal Size+ Documents
- Multiple Smaller Items at Once
- Posters
42”+ Wide Format Laminators
Wide format laminators are suitable for professional settings where high-volume and large-scale laminating is required. They are perfect for:
- Posters and Banners
- Displays
- Professional Presentations
Laminate Thickness
Laminating film thickness is measured in mil, which represents one-thousandth of an inch. The thickness you choose determines the durability and flexibility of your laminated item. Laminating films typically range from 1.5 mil to 10 mil.

Laminate Finish
A laminate’s finish impacts the project's appearance and texture. Different finishes offer varying levels of shine, glare, and resistance to wear and tear. Here are some popular laminating finishes to consider for your projects.
Glossy Laminate
Glossy laminate is the most common finish, providing a clear, smooth, and shiny surface. It gives your documents a professional look. This type of film is excellent for protecting your projects and can be used with dry-erase markers. However, the added shine can cause glare, especially in bright lighting or outdoor settings, which may not be ideal for signs or displays.
Matte Laminate
Matte laminate offers a non-glare finish, providing a look and feel similar to standard printing paper. This finish removes all shine and is perfect for documents that need to be easily readable under various lighting conditions. Matte laminating film provides the same level of protection as gloss film but with a unique, sophisticated appearance.
Soft-Touch, Satin & Silk Laminate
These premium laminates enhance the matte finish with a luxurious feel. The level of shine varies, with soft-touch being the most matte and silk the glossiest. These films are perfect for adding a tactile element to frequently handled items, making them ideal for upscale packaging, such as makeup products.
Luster Laminate
Luster laminate strikes a balance between glossy and matte finishes. It reduces glare while maintaining a subtle shine, similar to a fine glitter powder. The lightly textured surface refracts light, making images pop without overwhelming glare. This film is great for photos, posters, and display pieces.
Dry-Erase & Anti-Graffiti Laminate
Dry-erase laminate enhances the writable surface of gloss film, allowing for easy cleaning even after the ink has dried. It's perfect for reusable documents like activity sheets or chore charts. Anti-graffiti laminate takes this further by creating surfaces that can easily wipe away spray paint and other graffiti, making it ideal for protecting posters and flyers from vandalism.
Embossed, Textured, and Anti-Slip Laminate
These films are designed for heavy-duty applications, providing ultimate protection against scuffs, scratches, and wear. Textured laminates are perfect for indoor and outdoor signage, reusable displays, and floor or wall decals. Their durable surface withstands heavy foot traffic and repeated use, keeping your graphics looking pristine longer.
Adhesive Laminate
Adhesive laminating films allow you to add a sticky backing to your projects, essentially creating stickers.
Permanent vs. Repositionable
- Permanent Adhesive: Ideal for mounting signs or graphics that need to stay in place indefinitely.
- Repositionable Adhesive: Perfect for items that may need to be moved or adjusted, like store window signs.
Opaque vs. Clear
- Opaque Adhesive: Usually white, it prevents light from passing through, ideal for window graphics where no light should glow through.
- Clear Adhesive: Maintains transparency, allowing light to pass through, suitable for projects requiring a see-through effect.
