Lactips of France launches bio-based compostable sealant for dry food packaging
In February 2025, French biomaterial manufacturer Lactips announced the launch of its new CareTips® PFP344MAX sealant product, a paper coating designed for dry food packaging. The product is soluble in water and can be used in terminal paper. It uses 100% bio-based raw materials, combines compostability with high sealing performance, and provides a more cost-effective sustainable solution for the packaging industry.
It is understood that common raw materials for bio-based sealants include starch, cellulose, polylactic acid (PLA) or other polysaccharide derivatives. Cellulose itself needs to be chemically modified (such as carboxymethyl cellulose) to have sealing properties.
Market demand drives innovation
The current food packaging industry faces a dual challenge: both reducing environmental impact and controlling production costs. Benoît Berny, Product Innovation Manager at Lactips, said: "We have seen a significant increase in the market demand for packaging solutions that are highly sealable but do not require a grease barrier. The new sealant reduces raw material costs by optimizing the formula while maintaining excellent performance, helping customers achieve economic benefits in the environmental transformation."
Core advantages of the product
Environmental characteristics: 100% bio-based raw materials, home compostable, and does not contain harmful substances such as PFAS. Functional performance: Suitable for inert dry foods and secondary packaging, providing reliable sealing protection. Production adaptation: It adopts pre-dissolved granules and is compatible with existing industrial processing equipment. Compliance certification: It complies with the EU Food Contact Materials Regulation (EU 10/2011) and the composting standard EN 13432.
Technological breakthroughs
The sealant optimizes the molecular structure and increases the heat seal strength to 1.2 times that of traditional products while maintaining the inherent properties of bio-based materials. Laboratory tests show that the packaging integrity remains above 98% after 6 months of storage at 40℃/75%RH.
Industry application prospects
Lactips' innovative achievements provide new options for the packaging of baked goods, cereal snacks, dry goods and other products. Compared with traditional petroleum-based sealants, its carbon footprint is reduced by 65% and production energy consumption is reduced by 40%. The product has passed the verification test of major European food groups and is scheduled to be mass-produced in the third quarter of 2025.
