LDPE packaging for food businesses
Food packaging has one requirement the rest of the industry does not: you have to be able to prove what you bought. We run food work on virgin resin with lot-linked migration test reports, so your audit file is complete before anyone asks.

What each food category actually needs
Four food businesses, four different specs. This is the table we work from when someone calls.
- Written confirmation that the film is virgin resin with zero recycled content.
- A migration test report to IS 9845, taken from material in your lot, with your lot number printed on it.
- Confirmation that print is on the non-contact surface with food-safe inks.
- A lot number on the packing label that matches the report. Without that link, the report proves nothing about the bags in front of you.
The temperature question, answered once
This is the most common technical mistake we see in food packaging enquiries, and it is worth being blunt about.
- Cold and ambient: LDPE is ideal. It stays flexible down to minus 40 for short exposures, which is why it dominates frozen and chilled packing.
- Warm fill up to about 80 degrees Celsius: usually fine, but tell us, because it changes the film we run.
- Hot fill, boiling or microwave: not LDPE. It softens around 100 to 110 degrees and melts around 110 to 120. That is a PP or laminate job, and we will point you to it rather than sell you a failure.
If a supplier says yes to hot filling in plain LDPE without asking your temperature, that is a useful thing to have learned about that supplier.
