Description
Transparent BOPP film for labels is engineered specifically for the pressure-sensitive label industry. Unlike general-purpose BOPP packaging film, label-grade BOPP is produced to tighter tolerances on surface energy, dimensional stability, and thickness uniformity – all of which are critical for reliable performance on high-speed label converting lines and label application machines.
The film delivers the “no-label look” that has become a key design feature across the premium food, beverage, and personal care segments in Europe. When applied to a clear glass or transparent PET bottle, a transparent BOPP label becomes nearly invisible, giving the impression that the product itself is branded. This effect relies entirely on the optical quality of the base film, which is why label-grade BOPP is manufactured to especially tight clarity and haze specifications.
Converting and Application Performance
The film surface is corona treated to achieve consistent dyne levels that ensure strong adhesion of pressure-sensitive adhesive coatings during the label manufacturing process, and reliable bonding to a wide range of container surfaces during label application. Dimensional stability under tension is a key characteristic – the film does not stretch or distort on the converting line, which is essential for maintaining register accuracy in multi-colour printing.
Both one-sided and two-sided corona-treated versions are available. Two-sided treatment is used where the adhesive is applied to the back of the film by the label converter rather than supplied as a pre-coated laminate. The film accepts UV flexographic, solvent-based, and water-based inks used in the European label printing industry.
Frequently Asked Questions
What is the “no-label look” and how does BOPP film achieve it?
The no-label look refers to a label that appears to be part of the container itself rather than a separate applied element. When a high-clarity transparent BOPP label is applied to a clear glass or PET bottle using a clear adhesive, the label film is nearly invisible – only the printed graphics and any white ink used for opacity are visible to the consumer. Achieving this effect requires BOPP film with very low haze (under 1%) and high optical clarity, which is why label-specific grades are manufactured to tighter specifications than general packaging film.
How is BOPP label film different from BOPP packaging film?
Label-grade BOPP is produced to tighter specifications on surface energy, dimensional stability, and thickness uniformity. General packaging film can tolerate slightly more variation in these properties without affecting performance, but label converting requires very consistent surface dyne levels for adhesive bonding, tight thickness tolerance for uniform adhesive coating, and excellent dimensional stability to maintain print register across long runs.
Is transparent BOPP label film suitable for food contact applications?
Pressure-sensitive labels applied to the outside of food containers typically do not require full food contact certification because the label is not in direct contact with the food. However, if the label is intended for direct food contact applications, or if local regulations require it, NovoPacks can supply certified food contact compliant grades. Please specify your end-use requirements when enquiring.
Can this film be printed using UV flexographic inks?
Yes. Transparent BOPP label film is compatible with UV flexographic printing, which is the most common printing method for self-adhesive labels in Europe. The corona-treated surface provides the required dyne level for UV ink adhesion without primer in most cases. Solvent-based and water-based flexographic inks are also compatible. Rotary screen and digital label printing can be used with appropriate primer treatments.
What roll widths are available for BOPP label film?
BOPP film for labels is available in a range of slit widths to suit narrow-web label presses, which typically run widths from 250mm to 530mm. The film is supplied on cores compatible with most European label press configurations. Contact NovoPacks with your press width, core size, and desired roll diameter for a specific quotation.
