Seeking Lining Material for Metal Packaging in Food and Beverage Cans

• A material
• A product or a technology

A SpecialChem Client is seeking a lining material suitable for mechanical bending during the seaming process, resistant to temperature, a range of PH and oily/fatty environments, and should be chemically inert.

When in its final form, the material must:

• Form hermetic seal between the two metal surfaces
  • Metal can be coated or uncoated aluminum, ECCS [acronym for?] and tin-plated steel components typically used for metal packaging
  • Be evenly applied, with no bulk defect, surface defects, or thinning
• Resist to high vacuum packing (vacuum must not disturb liner placement); aseptic processing and in-pack processing pressure [specify pressure value]
• The lining material must comply, or have the potential to, with all relevant food contact regulations in the EU, EU member states, USA and Asia including China, both in terms of composition and migration
• The material must not be subject to classification as CMR 1A, 1B or 2

The lining material should be stable with typically packaged products:

It must not lead to any deterioration of the organoleptic quality of processed food or beverage. The lining material must be dry/stable within existing process times [specification required] or be implementable with an alternate curing process that uses less energy than current methods [need to describe current methods].

• Liquid – carbonated (or non-carbonated) soft drinks, beers and processed beverages, pH range from 2.5 to 8.0. Lining material must be suitable for aseptic, cold and hot fills, typical heat pasteurizing processes, and by processing with steam up to 121°C for 60 minutes. The lining material must be suitable for a range of can internal pressures.
• Solid, semi-solid or liquid food currently packed in metal food cans. The lining material must survive the double seaming process and the cooking process which uses steam processing for up to 131°C for 60 minutes or equivalent, pH range from 2.5 to 8.0. The lining material must be suitable for high fat products, (must not soften and be displaced).
• Maximum processing temperatures for Beverage containers are 80C.
• Target cost per square meter 2

• Concept materials at early stages of development cycle.
• Processes or products that don’t have the potential of being food contact approved for use in Europe and/or USA. 

• The SpecialChem Client prefers the material to be ready for use as supplied; i.e., no additives required at point of application.
• Full disclosure of constitutional materials/substances under a suitable NDA specifically for the purpose of regulatory approval will be required.
