Description
Thermosealable white BOPP film is the go-to flexible packaging material for snack foods, baked goods, coffee, and any product category where a clean, bright, opaque background is needed alongside reliable heat-seal performance. The film combines a high-whiteness, high-opacity BOPP substrate with a heat-sealable surface coating, eliminating the need for an additional lamination or coating step before the film reaches your packaging line.
Opacity levels typically exceed 85%, providing an excellent foundation for full-colour printing without any show-through of the product beneath. This makes the film particularly suitable for brands that rely on consistent, vivid pack graphics to drive purchase decisions in competitive retail environments. The white base also helps printed colours appear brighter and more accurate compared to transparent substrates.
Sealing and Line Performance
The thermosealable surface coating initiates sealing at temperatures between approximately 90 and 120 degrees Celsius and is engineered for clean, consistent seals on both vertical form-fill-seal (VFFS) and horizontal form-fill-seal (HFFS) packaging machinery. Seal strength is sufficient for the weight ranges typical of snack, cereal, and confectionery pouches without over-sealing or film distortion around the jaw area.
All food contact grades comply with EU Regulation (EC) No 10/2011, making the film suitable for direct contact with a wide range of food products including dry goods, fatty foods, and confectionery. The white pigmentation used is food-grade and migration-tested to European standards.
Frequently Asked Questions
How does thermosealable white BOPP differ from white polyethylene film?
Thermosealable white BOPP offers higher stiffness, better moisture barrier properties, and superior printing quality compared to white polyethylene of the same thickness. BOPP packaging tends to have a crisper appearance and better dimensional stability on the production line. Polyethylene is more flexible and puncture-resistant, which suits different applications – such as heavy bags or stretch-wrap formats – where BOPP would not be the right choice.
What printing methods work best on white BOPP film?
Flexographic printing is most common for white BOPP packaging in Europe, particularly for snack and food pouches. Gravure printing is also widely used where very high colour consistency is required across large production runs. The white substrate gives excellent colour pop with both methods and supports fine line detail and photographic imagery reproduction effectively.
Is thermosealable white BOPP film food-safe?
Yes, food contact grades comply with EU Regulation (EC) No 10/2011. The white pigmentation is food-grade titanium dioxide, which is a well-established and approved colourant for food packaging materials in the EU. Product-specific migration documentation can be provided for applications requiring formal compliance records.
Can this film be used for coffee packaging?
Yes. Thermosealable white BOPP film is used in coffee packaging, particularly for ground coffee and pod packaging where a bright white background is part of the brand aesthetic. For roasted coffee requiring a gas barrier to prevent staling, the film is often combined with a barrier layer in a laminate structure. NovoPacks can advise on suitable lamination partners depending on your shelf-life and oxygen barrier requirements.
What is the typical width and thickness range for this film?
Thermosealable white BOPP film is commonly available in thicknesses from 20 to 40 microns and in roll widths suited to both narrow-web label converters and wide-web flexible packaging lines. Standard core sizes are 76mm and 152mm. Contact NovoPacks with your specific width, thickness, and quantity requirements for a tailored quotation.
