10 ways to buy food-grade cling film

  1. Material selection
    Choose food-grade materials, such as PE (polyethylene) or PVC (polyvinyl chloride), to ensure non-toxic, harmless and odorless. There are mainly the following common cling film materials on the market today:
    Polyethylene (PE): Most widely used, offers good transparency, flexibility, and heat resistance for refrigeration, freezing, and microwave heating.
    Polyvinyl chloride (PVC): Less expensive but safety is debated, recommended avoiding.
    Polyvinylidene chloride (PVDC): Offers excellent freshness and barrier properties, ideal for long-term preservation of foods like meat and fruits, albeit at a higher price.
  2. Marking should be clear: recognize the QS logo and food-grade identification
    When shopping for cling film, be sure to check whether the logo on the product packaging is clear and complete. Formal food-grade cling film should be labeled with the following information:
    Manufacturer’s name and address
    Product name
    Executive standard number
    QS mark
    Food grade marking
    If any of the above information is missing from the product package, it is recommended not to buy it.
  3. Thickness Consideration
    Moderate thickness can provide better freshness. Usually, 0.01-0.02mm film is suitable for regular food packaging, and 0.02-0.03mm film is suitable for cooking and refrigeration.
  4. Transparency
    Choosing a film with high transparency provides a better view of the state of the food and prevents it from deteriorating undetectably.
  5. Toughness
    Considering the stretching and tearing during use, choose films with a certain degree of toughness to avoid easy rupture during use.
  6. Food contact safety certification
    Ensure that the cling film you buy has passed food contact safety certification, such as FDA (U.S. Food and Drug Administration) certification, etc., to ensure food safety.
  7. Temperature resistance
    If you need to use the cling film during the cooking process, make sure that it has proper heat resistance and is not prone to melting or releasing harmful substances.
  8. Quality and brand reputation
    Cling film products of well-known brands are usually more secure in terms of quality and safety. When shopping, you can give priority to cling film products of well-known brands.
  9. Instructions for use
    Carefully read the instructions for use on the product label for details such as the type of food to which it is applicable and how long it stays fresh.
  10. Packaging
    Choose the suitable packaging form according to your personal usage habits, such as rolls, boxes, etc.
