Question 1

What plastic is used for storage boxes?

Accepted Answer

Most household and commercial storage boxes are made from polypropylene (PP) impact copolymer for indoor and cold-storage units, or HDPE for budget outdoor/garden boxes. PP gives better drop impact at sub-zero temperatures and accepts pigments and prints well; HDPE is cheaper and is typically pigmented with carbon-black masterbatch for UV protection in outdoor use.

Question 2

Is plastic kitchenware safe for food?

Accepted Answer

Yes — modern plastic kitchenware sold in Europe must comply with EU 10/2011 food-contact regulations, with a Declaration of Compliance specifying the grade and any migration test results. Polypropylene is the dominant material for reusable food storage (it's microwave-safe and dishwasher-resistant); HDPE handles opaque containers and cutting boards. BPA-containing polycarbonate kitchenware has been largely replaced by PP and Tritan copolyester.

Question 3

Why does plastic furniture get brittle outdoors?

Accepted Answer

Untreated polyolefins (PP, HDPE) degrade under UV exposure — the molecular chains break, causing colour fading and embrittlement. Modern outdoor plastic furniture is formulated with HALS (Hindered Amine Light Stabilisers) and UV absorbers that extend the service life to 5+ years even under Mediterranean sun. Carbon-black-pigmented HDPE has the longest UV life because the pigment itself blocks UV penetration.

Question 4

Can I microwave plastic Tupperware?

Accepted Answer

Polypropylene (PP) containers labelled microwave-safe are designed to handle 130–140 °C briefly without deformation. The Tupperware-style food storage boxes sold in Europe are mostly PP. HDPE containers are not microwave-safe — they begin softening above 110 °C. Always check the symbol on the base of the container; the microwave-safe icon is the operative indicator, not the brand.

Question 5

Which polymers are most common for consumer goods & houseware?

Accepted Answer

Most common materials are Polypropylene, High-Density Polyethylene. Choice depends on regulatory requirements, mechanical performance, and cost target.

Question 6

What regulations apply?

Accepted Answer

Key regulations include EN 71 (toys), Food contact for kitchenware. 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.
