01

What does "food-grade" mean for ziplock bags?

Food-grade means that the film is approved for direct contact with food. The legal basis for this in the EU is Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food. It specifies which substances may be used in plastics for food contact and which migration limits apply to different foods.

Food-grade ziplock bags are made from pure LDPE granulate that meets the strict requirements of EU 10/2011. They contain no plasticisers, no bisphenol-based additives and no inks classified as harmful in the inner layer. This makes them fully suitable for all foods – from dry (muesli, nuts) through moist (salad, meat) to fatty (cheese, sausage).

The following applications are typical: pre-portioning food in the professional kitchen, storing dried fruit or spices in the hobby kitchen, freezer portioning of meat and fish, packaging baked goods or pralines, and much more. On request we supply the declaration of conformity (Declaration of Compliance) for the documentation of your HACCP or supplier assessment.

Your advantages with food-grade ziplock bags from Elke Plastic

Since 1972 we have imported packaging bags directly from the manufacturer and know the legal requirements for food contact materials. For you this means: certified film quality with seamless documentation. On request we supply the declaration of conformity with migration data that you need for your HACCP file or your supplier assessment.

EU 10/2011 is complex – not every LDPE film is automatically approved for all food contact. For high-fat or solvent-containing foods, stricter migration limits sometimes apply. Our packaging specialists advise you on which variant is the right choice for your specific contents. For special requirements (e.g. for acidic foods with more than 4 hours of contact time) we refer you to the appropriate special film.

Dispatch is from our German warehouse. Stock items in standard sizes are available immediately; bulk orders are scheduled in advance. No minimum order value. Catering and food-trade customers receive tiered pricing and, in some cases, direct delivery within the region. Free samples for advance testing are a matter of course.

Frequently asked questions about food-grade ziplock bags

Are all ziplock bags automatically food-grade?

No. Food-grade status requires a specific choice of material and production-accompanying testing. Standard ziplock bags from the industrial sector may contain additives that rule out food contact. Always look for the explicit note "food-grade to EU 10/2011".

What is a declaration of conformity (DoC)?

The Declaration of Compliance is a document from the manufacturer confirming compliance with EU 10/2011. It lists the approved food categories, the migration tests and the contact conditions. For HACCP-certified businesses it is usually a mandatory document in the supplier assessment file.

Are the bags suitable for all foods?

LDPE bags with EU 10/2011 conformity are approved for most foods – dry goods, meat, vegetables, baked goods. For extremely fatty or alcohol-containing products (e.g. oils, spirits), migration limits may require a different film. We are happy to advise on special applications.

Can the bags be frozen?

Yes, LDPE is cold-resistant down to -40 °C – well below freezer temperature. For freezer applications we recommend 70 micron bags or thicker, as the film can otherwise become brittle at very low temperatures.

Are the bags microwave-safe?

Generally NOT recommended. LDPE melts at over approx. 105 °C, which is easily exceeded in the microwave. For microwave-safe food bags there are special PP bags – please ask us about special requirements.

How long does food keep in a ziplock bag?

In the fridge, typically 3–7 days for fresh produce; in the freezer, 3–12 months depending on the food. Shelf life depends above all on the contents – the packaging itself only affects the oxygen and moisture barrier. For maximum freshness we recommend removing the air before sealing.

Are films containing plasticisers unlawful?

Plasticisers may only be used in approved quantities and for certain foods. Pure LDPE films typically contain no plasticisers at all. For food contact, PVC films with high plasticiser contents are legally problematic.

Can I use the bags for sous-vide cooking?

No. Sous-vide requires special films with temperature resistance above 80 °C. Standard LDPE is not suitable for this. For sous-vide applications we recommend special PA/PE vacuum films.

Is printing with a food logo available?

Yes, we offer printing with food-grade inks. The EU food logo (glass and fork) may be used by all suppliers whose bags comply with EU 10/2011. Please ask us about custom printing.

What applies to direct sales to end customers?

For farm shops, direct sales and craft businesses the same regulations apply as for industrial packaging – only small-quantity producers may use certain simplifications. What matters is the EU 10/2011 conformity of the bags and the mandatory information (FIC) on the end product.

Are sustainable food bags available?

Yes, for food we offer bio-PE variants in food-grade quality. Bio-PE from sugar cane is chemically identical to conventional PE and fully food-grade. PCR/recyclate variants are currently still in the test phase for food-contact suitability and are not approved for direct food contact – for food, please choose virgin material or bio-PE.
