Specific Compliance Standards for Food Grade Stretch Film

Acceptable Polymers for Food Contact Applications

Food grade stretch films should be made from polymers that are approved for food contact applications. Some commonly accepted polymers include:

  • Low-density polyethylene (LDPE)
  • Linear low-density polyethylene (LLDPE)
  • High-density polyethylene (HDPE)
  • Polyvinyl chloride (PVC)
  • Polypropylene (PP)
  • Polyethylene terephthalate (PET)

Using approved polymers ensures that the film does not introduce harmful substances into the food.

Prohibited Substances and Additives

To ensure food safety, certain substances and additives are prohibited in food grade stretch film due to their potential health risks. Examples of prohibited substances and additives may include:

  • Heavy Metals: Heavy metals such as lead, mercury, cadmium, and chromium are strictly prohibited due to their toxicity and potential adverse health effects.
  • Phthalates: Certain phthalates, such as DEHP (diethylhexyl phthalate), DINP (diisononyl phthalate), and DIDP (diisodecyl phthalate), are prohibited due to their potential endocrine-disrupting properties.
  • Bisphenol A (BPA): BPA, a chemical commonly used in plastics, is prohibited in food grade stretch film due to its potential hormone-disrupting effects.
  • Vinyl Chloride Monomer (VCM): VCM, which is used in the production of PVC, is prohibited due to its carcinogenic properties.
  • Chlorinated Paraffins: These substances, used as flame retardants, are prohibited due to their persistence and potential environmental impact.

Strict adherence to the prohibition of these substances and additives helps ensure that the food grade stretch film does not pose any health risks to consumers.

Maximum Allowable Levels of Chemicals that can Migrate into Food

Food grade stretch film must comply with maximum allowable levels of chemicals that can migrate into food. Regulatory authorities define specific migration limits to safeguard consumer health. Examples of chemicals with migration limits include:

  • Benzene: A known carcinogen, benzene must not exceed the specified migration limit in food grade stretch film.
  • Acetaldehyde: This compound, which can affect taste and odor, should be within acceptable migration limits.
  • Acrylonitrile: Acrylonitrile, a potentially toxic compound, must not migrate above the defined limit.
  • Epichlorohydrin: Epichlorohydrin, used as a cross-linking agent, should not exceed the specified migration limit.
  • Formaldehyde: Formaldehyde, a common preservative, must be within the acceptable migration limits.

Compliance with these migration limits ensures that the food grade stretch film does not introduce harmful chemicals into the food and maintains the highest standards of food safety.

Testing Methods to Determine Migration Levels

To verify compliance with migration limits, food grade stretch film undergoes testing methods to determine the levels of chemical migration. These testing methods may include:

  • Overall Migration Testing: This method measures the total amount of substances migrating from the film into food simulants, such as water or ethanol, under specific conditions.
  • Specific Migration Testing: This method targets specific substances of concern and determines their migration levels into fatty food simulants.

By employing appropriate testing methods, manufacturers can ensure that their food grade stretch film meets the required migration limits and guarantees the safety of the packaged food.
