The packaging revolution

The SuniBarrier revolution: a range of paper and cardboard for packaging without plastic film

Guyenne Papier is developing a coating process for transforming “traditional” paper into wrapping paper.
This is a real revolution for the industrial and agri-food sectors, because these packaging papers have barrier properties, comparable to those of conventional plastic packaging, which are not recycled enough or badly and are generally sources of pollution. 

SuniBarrier offers a range of papers for eco-responsible packaging with various properties : barrier to odours, grease, water, humidity and vapours, all heat-sealable.
All papers in the SuniBarrier range are also designed to be in direct contact with food products and offer a natural alternative to polluting and non-recyclable packaging.
The SuniBarrier range even has a 100% biosourced, repulpable and 100% biodegradable barrier paper : GreenBee

Packaging for

Whether you are a manufacturer, cardboard maker or food industry professional, the SuniBarrier range meets the daily problems you are likely to encounter.

Thus, it is perfectly adapted to the needs of :

  • Ingredients manufacturers (tea, sweets, etc…),
  • Biscuit manufacturers,
  • Manufacturers of moisture-sensitive products,
  • Supermarket chains in the delicatessen, butchery and fish departments,
  • Printers, packaging designers, cardboard manufacturers.

SuniBarrier committed to preserving nature

Finding a paper that can replace plastic is not a new idea since it is ultimately going back to the very origin of paper, which has always been used to wrap food and organic materials. Guyenne Papier wants to replace plastic with a natural and recyclable product, in line with today’s major ecological challenges.

These papers for packaging thus have barrier propertieswithout plastic film, and which can be recycled once they are no longer used.

4 years of research to achieve this innovation

Guyenne Papier’s R&D department has always developed and formulated innovative solutions in the packaging sector.
Based in the Dordogne, he has now developed a whole range of papers that are not only barrier to water, grease, vapor but also heat-sealable and more than 95% recyclable, even going beyond the requirements the highest in the EU for recyclability rates.

And to anticipate the health changes of tomorrow, and unlike competing products, Guyenne Papier’s products are fluorinated resin-free, chlorine-free (PVdC), PVA-free and plastic film-free (PE – Polyethylene or other PET – Polyethylene Terephthalate free) .

SuniBarrier is the result of several years of research, industrial trials and partnerships. It is in fact a very precise coating process which makes it possible to improve the properties of traditional paper, to make it a paper for resistant packaging, which has the advantage of retaining the single-material dimension of the paper. Thus, SuniBarrier papers contain no PE, no PVC, no PET or PP (polypropylene). They can be reprocessed without polluting, in paper recycling channels.



The revolution of good resolutions

The AGEC law aims to significantly reduce the use of packaging containing plastic by 2025, and completely eliminate it by 2040.

« Art. L. 541-10-17.-France has set itself the goal of reaching the end of the marketing of single-use plastic packaging by 2040.”

The SuniBarrier range thus responds to the problem of companies concerned about their energy production, but also in the long term, in general, to give the industry and agri-food sector the real possibility of complying with the anti-waste environmental law. Moreover, for the brand image of a company, the use of eco-responsible packaging is a real asset and a CSR argument to be valued. The regulations are thus in line with the paths traced by Guyenne Papier several years ago, through our environmental policy which aims for 100% paper.
