You can use cold
laminating film without machine since it relies on pressure-sensitive adhesives rather than heat. The transparent matrix adheres to the substrate tenaciously by exerting strong force on the visco-elastic mucilage. Frankly, it is a highly sensual affair that brings me close to the chemistry behind it, although there is always a terrifying threat of entrapment of rogue air bubbles. I use high-quality VIZLENT vinyl and PET stocks and the instantaneous tack of these pressure-sensitive polymers is simply breathtaking in my opinion.
Indeed, to press our specialized eggshell paper, or our fragile thermal transfer labels, without a motorized press will require of us great, unswerving patience and a dust-free atmosphere. Suddenly, rubbing away that last perfect edge, the consequent gush of pure, untainted professional gratification intoxicates me. It demonstrates the undefeated, frictionless strength of contemporary engineering, and I adore the presence of that crystal-clear change.
How can I use cold laminating film without machine?
Learning to apply pressure-sensitive over-laminates manually is literally a challenge to stoicism and manual skill! I always begin by pasting the upper part of my printed vinyl to a flat and stable workbench with a small piece of masking tape… Any movement of the substrate during the bond is a calamity.
By peeling back approximately one inch of the release liner I expose the aggressive adhesive and then go ahead to center it on the leading edge of my graphic. It is a stressful situation when one wrong degree of misalignment would spoil an otherwise good PET or BOPP label!
What can I use as a substitute for a laminating machine?
In case you do not have some fancy motorized unit, do not worry, there is no shortage of workarounds in the form of analog, and I find them quite surprising in terms of efficiency with smaller label projects! My favorite squeegee is a heavy-duty felt-edged squeegee; this offers the localized force necessary to cause the adhesive to be applied and not leave a scratch on the surface of the film. I have even resorted to a common rolling pin in the kitchen, which seems ridiculous, but it is very even in weight, and thus does not leave gaps in silvering. The trick is to imitate the even pressure of a mechanical roller that is permanent.
In flat substrates such as cardstock or rigid vinyl, a basic wide rubber brayer, as found in printmaking, is miraculous in terms of creating a smooth, no-bubbles bond. It is gratifying to observe how the translucent layer is soaked to perfection with the weight of a hand tool.
Do you need special pouches for cold lamination?
Cold lamination uses a continuous roll of strong PET or vinyl pellicle coated with a visco-elastic, pressure-sensitive mucilage (unlike thermal lamination that may be done using pre-sealed sleeves). You do not even really need a special pouch in the old sense; but you need an over-laminate, in which is an aggressive, frictionless adhesive which coalesces when impregnated physically.
The fact that our VIZLENT films are able to provide protection to a fragile B2B substrate without thermal activation is something deeply emotional to me. Certainly, an attempt to activate a normal heat-activated pouch without a machine is a disaster- it will not bond. It is such a sense of pure, unadulterated chemical freedom that you find in the realization that you can control the process without having a pre-made pocket.
How to manually laminate stickers?
In order to hand roll an over-laminate onto a cold surface, you must have a clean, flat surface to first adhere your printed material. Unpeel the siliconeized release liner around an inch, and position the aggressive VIZLENT vinyl or
PET pellicle with the upper side of your
label stock, this is a moment of intense concentration. I am shattering my heart when I see graphics destroyed by one air bubble! Indeed, apply with a stiff felt tip squeegee, making heavy strokes, one over the other, pushing the viscoelastic mucilage slowly into microscopic crevices.
The pressure sensitive polymers suddenly coalesce to form an impervious obstacle to moisture and abrasion. I am filled with deep victory as that crystal-clear matrix expands flawlessly on our
eggshell paper of specialized sticker. This is a ballet of touch between hand and polymer that demonstrates the idea that it is not necessarily a machine to provide protection of industrial quality!
