Do all laminators do the same job?

No! There are many variables to consider when looking at your next laminator such as; thickness of laminates/ substrate, average meter’s per hour/day, how often you need to change laminates, ease of operation and fine-tuning.

What do I look for in a new laminator?

Chassis – make sure it is sturdy and doesn’t feel insecure or wobbly.
Rollers – Cambered rollers are best for a wide range of laminates over a long distance whereas parallel rollers are suited to thicker laminates at shorter run lengths.

Laminating Process


Issues that can occur during the lamination process and why

– Silvering on the film surface (light random markings after lamination), can occur when not enough heat has been applied to the top heated roller or not enough pressure has been applied to the film.
– Curling on the edges of the film after the laminating process is the result of too much tension being applied to the mandrels that hold the laminating film. The other possible reason for the curling is too much pressure applied on the laminating rollers.
– Slower is better when laminating, the longer the film is in contact with the rollers the better the lamination process will be.

What is Silvering?

Silvering is a term given to the finished appearance. This can occur when the adhesive has not reached the desired temperature or hasn’t been given enough time to ‘wet out’ leaving a milky finish due to tiny air bubbles.

How much pressure or heat is required?

This depends on what film/substrate you are using. Most vinyl manufactures will have a working range of pressure and temperatures. As a general guide 40 – 60⁰C at 5-6kg pressure for an 80-microns self-adhesive vinyl.

What is a SUBSTRATE?

Substrate is a an underlying substance or layer on which printed materials or a mounting board are used injunction when laminating.

What is a ACRYLIC Glue?

An acrylic glue is a resin-based adhesive that is comprised of acrylic or methyl acrylic polymers. This Adhesive is most commonly found in most but all laminating film and vinyl. Another adhesive is called POLYETHYLENE it is also called (PE) is a common adhesive most frequently found in thermal films. Appears cloudy then ultra-clear when liquefied with heat, finally becomes a flexible solid when cooled down.

What is POLYESTER?

Polyester is a basic type of plastic that forms the strength of most ‘Thermal’ laminating films. Sometimes referred to as Polyethylene terephthalate (PET). Also, can be found in many cold or PSA films.

What does PSA mean?

PSA means “Pressure Sensitive Adhesive”, is an adhesive which forms a bond when pressure is applied to marry the adhesive with the adherend. No solvent, water, or heat is needed to activate the adhesive. This type of adhesive is commonly found in cold films and some thermal films.
