Learn What Settings The Laminator Should Be On- Heat Settings Or Cold Settings
The laminating process according to the hot and cold, pressure conditions and materials can be divided into two forms cold lamination and hot lamination.
Cold laminating directly relies on the adhesive to bond the film to the image by applying pressure. Hot laminating technology requires additional heating on top of the pressurization to ensure that the film and the image can fully adhere to each other.
Heat settings or cold settings?
The films used for cold setting and heat setting are different. The cold settings uses pressure-sensitive adhesive film, whose main components are polyethylene and adhesive, with good adhesion, transparency, and aging resistance.
The hot settings uses a heat-sensitive film with an outer layer of highly transparent polyester film and an inner layer of fusible adhesive.
Factors affecting the laminating temperature
The laminating temperature of the laminator needs to be determined according to the different laminating materials, and in general, the recommended temperature is between 60℃-120℃.
1. Type of laminating material
Different types of laminating materials require different temperatures, such as common BOPP film laminating temperature is generally between 70℃-100℃, while the PET film laminating temperature needs to be higher, generally between 100℃-120℃.
2. Thickness of the laminating material
Generally speaking, the thicker the laminating material is, the higher the temperature is because a higher temperature is needed to closely fit the laminating material to the material being laminated.
3. Nature of the material
The nature of the material to be laminated will also have an effect on the temperature setting. For example, if the material is fragile, the laminating temperature needs to be lowered to avoid damage; if the material is a high-temperature material such as metal foil, the laminating temperature needs to be raised to ensure the laminating effect.
How to set the right laminating temperature for heat laminating?
1. Determine the laminating temperature according to different laminating materials.
Different types of laminating materials require different temperatures, it is recommended to understand the nature and requirements of the laminating materials used, and then determine the optimal laminating temperature according to the characteristics.
2. Conduct trial lamination test
Before actual use, a trial laminating test can be conducted to determine the optimum laminating temperature. Set the equipment to the preset temperature, carry out a period of trial laminating, and observe the effect of laminating, if you find problems, you can gradually adjust the laminating temperature until you get the best laminating effect.
Cold lamination does not require setting temperature?
In fact, when cold laminating, the appropriate heating temperature will not destroy the material, but also help the film and the picture more closely. Cold laminating temperature can be controlled below 60° to achieve the best laminating effect. However, the specific temperature varies depending on the material.
FAQ
How long does it take for a laminator to heat up?
The warm-up time depends on the machine's heating technology and the thickness of the pouch being used:
Standard Office/Home Models: Typically take 3–5 minutes. A "Ready" indicator light will signal when the rollers have reached the set temperature.
Fast-Heating Models: High-end or modern units can heat up in as little as 60 seconds.
Large Format/Industrial Roll Laminators: These may require 10–15 minutes to ensure the large rollers are heated evenly through to the core.
Pro Tip: If you notice a "cloudy" finish on your first document, the machine may not be hot enough yet. Wait an extra 60 seconds after the "Ready" light turns on for the best results.
What is the difference between Hot and Cold Laminating?
The primary difference lies in the adhesive activation method and the sensitivity of the document.
Hot Laminating (Thermal)
How it works: Uses heated rollers to melt the glue on the film, bonding it to the paper.
Best for: Standard paper documents, certificates, and items that need a permanent, high-strength bond.
Pros: Most durable and cost-effective for high-volume use.
Cons: The heat can damage thermal paper (like receipts), wax-based inks, or very old, delicate photos.
Cold Laminating (Pressure-Sensitive)
How it works: Uses pressure instead of heat to bond film that has a "sticky" adhesive backing.
Best for: Heat-sensitive materials, vinyl stickers, outdoor signage, and ink-jet prints that haven't fully cured.
Pros: No warm-up time required; safe for all document types.
Cons: The film (consumables) is typically more expensive than thermal film, and there is a higher risk of silvering (tiny air bubbles).
What is the difference between BOPP film and PET film?
The main difference between BOPP (Biaxially Oriented Polypropylene) and PET (Polyester) film lies in their flexibility and durability: BOPP is softer, easier to fold, and more cost-effective, making it ideal for flexible packaging and book covers; whereas PET is stiffer, more transparent, and offers superior heat resistance and scratch protection, making it the preferred choice for high-durability items like ID cards and menus.
