What materials are used for Labels?
In our previous article, we looked at the 4 stages a label manufacturer uses in the label manufacturing process. The first stage is preparing the label stock which entails decided on either paper or film material for the label.
Paper is a natural product made from pulp or wood. All paper used by label manufacturers is measured by basis weight and grade. A wide variety of paper grades are used by label manufacturers in order to service different markets. EDP or uncoated paper is used for Dot Matrix or impact printers. High gloss paper is for prime labels or high end process work labels. There are also semi-gloss, coated and metalized paper options available which label manufacturers can use.
Film is a synthetically manufactured product that is often preferred by many label manufacturers for use in printing labels. Film labels can withstand very harsh environments and are available in a variety of options including hard, soft, flexible, rigid, thick and thin. Various types of film material include:
• Polyester Film– These are used under the hood of cars for example as they withstand harsh environments.
• Vinyl Film – vinyl has lower durability and tends to shrink with age.
• Polypropylene Film – Designed for indoor use
• Polyethylene Film – These are used on shampoo bottles for example
• Tyvek Film – Non tearing and good for curved surfaces.
• Transcode Film– Used for thermal applications
• Aluminium Foil Film – These are used for very harsh environments
• Synthetic Film – These are very high strength films.
The next consideration a label manufacturer has is that of which adhesive to use. Categories of adhesives include:
•Initial Tack – for instant holding power of the label
• Ultimate Adhesion – the maximum holding power of the tack is only achieved after a period of time.
• UV Resistance – The ability to be exposed to UV Rays without losing adhesion or changing colour.
• Solvent Resistance – the ability to withstand solvents without losing adhesion.
• Minimum Application Temperature – the minimum temperature that the adhesion will withstand.
• Service Temperature – the minimum and maximum temperature the label can be exposed to after being applied. For example frozen foods will need a stronger adhesive to room temperature food packaging.
