Antioxidant active packaging films were prepared with low density polyethylene (LDPE) being incorporated with α-tocopherol loaded MCM-41 mesoporous silica with different pore sizes.

Blending collagen, whey protein, and methylcellulose can be used as a strategy to produce biodegradable films for food packaging. Methylcellulose increases tensile strength, barrier, and thermal properties, while collagen promotes the elongation at break and whey protein presents lower solubility in water. These biodegradable materials have potential for use as soluble sachets, oil containers, and/or capsules for instant coffee.

The presented work aims to influence the forming behaviour of uncoated and polyethylene terephthalate (PET)-coated paperboard with additives like water, gelatin and soap. Furthermore, the differences in the mechanical behaviour of coated and uncoated materials are investigated. The investigations showed that the overall forming behaviour is affected by the mentioned additives and can be improved.

The Hot-Tack and seal strength windows of mono-polyolefins and paper-based materials show their basic sealability but new challenges are faced on traditional form-, fill-, seal-machines. The sealing temperature of mono-polyolefins is found close to the range in which shrinkage appears and generates high demands on the temperature control of machines. The sealing of paper-based materials is also possible in suitable processing times but requires thorough moisture control and compromises in the final seal strength.

Recoveries of BPA in films and foods were 88.87%–97.29%. BPA exhibited the highest migration rate from films to n-hexane after 24-h immersion. The BPA content in apple from film reached 0.403 mg kg⁻¹ after 4-month storage.
