FAQs

Q: What is the best film for food packaging?

A: The best film for food packaging depends on the product and its requirements. Film & Foil supplies a range of options including BOPP, OPP, PET, and laminated films. BOPP and OPP films are commonly used for fresh produce and bakery items due to their flexibility and clarity, while PET and laminated films are better suited for applications requiring strength, durability, and extended shelf life.

Q: What is BOPP film used for in packaging?

A: BOPP (biaxially oriented polypropylene) film is widely used in food packaging, labels, and overwrapping. It is ideal for products such as snacks, bakery goods, and fresh produce because it offers high clarity, good strength, moisture resistance, and excellent printability.

Q: What is the difference between PET and OPP films?

A: PET (polyester) films are stronger, more durable, and offer higher heat and chemical resistance, making them suitable for demanding applications and lamination. OPP (polypropylene) films are more flexible, lightweight, and seal at lower temperatures, making them ideal for flow wrapping and high-speed packaging. PET is typically chosen for performance, while OPP is preferred for efficiency and cost-effectiveness.

Q: What is the best lamination film for digital printing?

A: The best lamination film for digital printing depends on the desired finish and durability. OPP films are a cost-effective option for standard print jobs, while PET films provide a higher-quality finish with greater durability and resistance. Film & Foil supplies both options for thermal, digital, and water-based lamination processes.

Q: How do you extend shelf life with packaging films?

A: Shelf life can be extended by using laminated and barrier films that protect products from moisture, oxygen, and contaminants. Multi-layer laminated films improve durability and provide enhanced barrier properties, helping to maintain freshness and product quality for longer periods.

Q: What are the benefits of flexible packaging over rigid packaging?

A: Flexible packaging offers several advantages over rigid packaging, including reduced material usage, lower transport costs due to its lightweight nature, and greater customisation options. It also allows for efficient production processes such as slitting and perforation, while providing strong visual appeal and effective product protection.

Q: What is modified atmosphere packaging (MAP)?

A: Modified atmosphere packaging (MAP) is a technique where the air inside a package is replaced with a controlled mixture of gases such as carbon dioxide and nitrogen. This process helps slow down spoilage and extend shelf life. MAP is typically used with high-barrier and lidding films to maintain product freshness in applications such as fresh produce, meat, and ready meals.
