Question 1

What plastic is used for rigid food packaging in Europe?

Accepted Answer

Polypropylene (PP), PET and high-impact polystyrene (HIPS) cover the vast majority of rigid food packaging on European supermarket shelves. PP handles tubs, lids and ovenable trays; PET (in its APET sheet form) is thermoformed into fresh produce trays and clear punnets; HIPS is used for opaque yogurt and dessert pots. All three meet EU 10/2011 food contact requirements with grade-specific Declarations of Compliance.

Question 2

Is plastic food packaging safe for hot food?

Accepted Answer

Polypropylene is the standard material for plastic food packaging that contacts hot or microwaved food — it stays dimensionally stable up to 100–110 °C continuously and tolerates microwave use. PET deforms above 70 °C unless it has been crystallised (CPET), in which case it withstands oven temperatures up to 220 °C. HIPS and APET are for cold and ambient applications only.

Question 3

Is rigid plastic food packaging recyclable?

Accepted Answer

PET trays and PP tubs are mechanically recyclable in well-functioning collection systems. Recyclability is highest when the format is monomaterial — multi-layer barriers, dark pigmentation and bonded labels all reduce recyclate value. Under PPWR's design-for-recycling rules from 2030, packaging that contaminates major recycling streams (notably PVC mixed into PET sortation) faces phase-out.

Question 4

What is the best plastic for fresh produce trays?

Accepted Answer

APET (amorphous PET) sheet thermoformed into trays is the European market standard. It offers the optical clarity needed for visual merchandising in chilled cabinets, accepts 30–50% recycled content (rPET), and seals well to lidding films for modified atmosphere packaging. Monomaterial PP trays are growing in share where PP/PP recyclability is the priority under PPWR.

Question 5

Which polymers are most common for rigid food packaging?

Accepted Answer

Most common materials are Polypropylene, Polyethylene Terephthalate, General-Purpose Polystyrene. Choice depends on regulatory requirements, mechanical performance, and cost target.

Question 6

What regulations apply?

Accepted Answer

Key regulations include EU 10/2011, FDA 21 CFR 177, EFSA opinion list. Suppliers must provide a Declaration of Compliance documenting that the specific grade meets the applicable standards.

Question 7

What lead times can I expect?

Accepted Answer

Distributor stock items: 1–3 days. Producer-direct prime: 1–4 weeks. Off-spec or near-prime spot lots: same week. Plan inventory accordingly.
