Food Safety

  • CBD.SEALS

    • Seals for the food safety industry are sealing materials and components used in food processing, packaging, storage and transportation. We meet stringent hygiene standards and safety requirements and have passed FDA and EU 1935/2004 standards to ensure that food products are not contaminated and maintain their quality and safety.

    Material selection

    Food-grade materials: the seals must be made of food-grade materials, such as food-grade silicone rubber (VMQ), food-grade polyethylene (PE), food-grade polypropylene (PP), food-grade polytetrafluoroethylene (PTFE) and so on.

    Non-toxic and odorless: the material must be non-toxic and odorless, and will not affect the taste and odor of the food.

    Chemical resistance: able to resist the erosion of acid, alkali, grease and other chemicals in food.

    Temperature resistance: able to maintain performance in the temperature range of food processing and storage, including low-temperature freezing and high-temperature cooking.

    Design requirements

    Hygienic design: Seals should be designed to be easy to clean, with no dead space and less likely to accumulate food residue.

    Sealing performance: Ensure effective sealing under all conditions to prevent food leakage and external contamination.

    Abrasion and ageing resistance: maintain their functionality during frequent use and long-term storage.

    Compatibility: Seals in contact with food must be compatible with food packaging materials and not react chemically.

    Manufacturing process

    Molding: suitable for the manufacture of rubber and certain composite seals.

    Injection molding: suitable for the manufacture of certain plastic seals.

    Machining: for the manufacture of metal and polymer seals.

    Surface treatment: the surface of the seal requires special treatment, such as polishing, plating, etc., to improve its hygienic properties.

    Testing and validation

    Food contact test: simulate food contact conditions to detect whether the seals have harmful substances migrated.

    Leakage test: Leakage detection through water or other media to ensure that the seals have no leakage.

    Environmental testing: Seal performance is tested in simulated food processing and storage environments.

    Lifetime test: Evaluate the service life of seals through accelerated aging tests.

    Application Examples

    Food packaging seals: such as the sealing of food bags, cans, bottle caps, etc., to ensure that the food is not contaminated during the packaging process.

    Food processing equipment seals: such as the sealing of mixers, filling machines, sealing machines, etc., to prevent food from being contaminated during processing.

    Food storage and transportation sealing: such as the sealing of refrigerated trucks, refrigerated boxes, food containers, etc., to maintain the freshness and safety of food in the storage and transportation process.
