Formulated high barrier adhesive for flexible package - RUICO

In Wet Bond lamination a coating is applied to one or more of the webs which are then combined while the coating is still in a liquid form. This type of lamination can take one of several different forms.

Using a water or solvent carrier based adhesive:

• adhesive is applied to one or both of the webs
• the webs are combined • after lamination the water or solvent is removed by passing the laminate through a drying process
• at least one of the webs needs to be permeable/porous so the water or solvent can escape
• the adhesive is typically applied to the non-porous web so that it stays on the surface
• in certain cases, particularly where light water based adhesives are used in conjunction with an absorbent web, drying may not be required to remove the water

Water Based Adhesive can be formulated to be Very Strong & Fast Setting and bond to a variety of porous and non-porous substrates including  UV,  Clay Coated and  SBS Papers,  Films,  Foils,  Woods,  Plastics,  Corrugated material,  Coated board and  Vinyl.

All of our Water Based Adhesives for the food & beverage packaging industry meet the requirements of the  FDA Adhesives regulation: 21CFR175.105, for Direct & Indirect Food Additives.

Flexible packaging has enjoyed tremendous market growth in the last decade as it holds particular appeal to both retailers and consumers alike. Retailers know that modern customers make rapid purchasing decisions based on the visual appeal of the packaging material. Advances in printing and coatings have allowed for almost unlimited customizability. In particular, matte coatings, haptic coatings and metallic coating have brought a richness in appearance that was not previously possible with plastic and paper substrates.

Although flexible packaging is already an efficient means to bring consumer products to market and its high product-to-package ratio supports source reduction,there is room for improvement with regard to sustainability. In particular, its reliance on multi-layered, plastic structures derived from fossil-fuels along with its poor recyclability are big challenges.

The different layers of material used in flexible packaging serve different functional requirements such as barrier properties, heat sealability or aesthetic effects. Multi-layered structures often include laminated or extruded polymeric films or foils—at the end of the product’s life cycle, these materials cannot be separated from one another for reprocessing and instead the whole construction is often landfilled. Finding an alternative construction that meets the functional requirements yet is more easily recyclable, repulpable or compostable is critical to delivering a solution.

Our barrier coatings are formulated to provide enhanced moisture vapor transmission rate (MVTR), oxygen transmission rate (OTR), moisture resistance (Cobb), and oil / grease resistance (OGR) to coated and non-coated paper and board substrates. Coatings may also be used on filmic substrates after appropriate treatment or application of primers. Select grades are compliant with FDA regulations for food contact including 21 CFR 176.170 and 176.180 as well as EU regulations. Coatings are formulated for a variety of coating methods including rod coating and printing press applications.
