Seeking Eco-friendly, Waterproof, Food-grade Liner Material to Replace Plastic Film

Background / Description

Packaging solutions are important across all industries as it protects the goods from potential risks that can affect its performance. In the food and beverage (F&B) industry, it is essential to avoid any form of spoilage during transportation and storage to maintain the taste and quality of the food. Therefore, packaging solutions used for F&B purposes need to be well constructed for the preservation of food. Plastic films are often used as one of the components in packaging solutions. Its flexibility, good barrier properties and high-performance properties allows for them to be incorporated into food packaging solutions. However, plastics take a long time to undergo degradation and are often the cause of environmental pollution.

The company is seeking a high-performance, eco-friendly and waterproof liner or coating as an alternative to PVC films for a packaging box. The new material (~0.3mm in thickness) will be used to line both the internal and external areas of the box derived from natural fibers. As the box is purposed for transportation and storage of temperature-sensitive F&B goods, this material must be UV-resistant and able to act as a reinforcement for the walls of the box. It should also be cost-effective, optically transparent, exhibit high strength and flexibility and prevent leakages due to the continual contact with ice and food items.

Technical Specifications

The proposed material should meet the following criteria:

  • Certified compostable or biodegradable in accordance with ASTM standards
  • Waterproof
  • Validated food-grade/food-safe by FDA
  • Exhibit high tensile and impact strength
  • Strong UV resistance
  • Good puncture resistance
  • Transparent
  • Cost-effective
  • Lightweight
  • Able to withstand temperatures from -20°C to 75°C


 Ideal specifications:

  • Permeance: <0.5 perms
  • Water absorption: max. 0.5 %
  • Tensile strength: 13 MPa
  • Impact strength: min. 1 
  • Able to retain >90% of tensile strength after 1 year of UV exposure
  • Puncture resistance: >50 N
  • Target price: ~USD 5/m2
  • Density: ~1 g/cm3

Note: The figures stated above are provided as a guide to any potential technology providers and are not absolute requirements.
