Short answer

HDPE for opaque, tough, chemical-resistant bottles; PET when the product must be seen; PP when it needs heat resistance or a semi-translucent look; PETG for the glass-look jar. HDPE is the usual body for shampoo, shower gel and household cleaners, and bleach, alkalis and concentrated surfactants belong in polyethylene.

HDPE vs PET

Choose HDPE when the bottle has to be opaque and tough: it is chemically resistant, and it is the usual body for shampoo, shower gel and household cleaners. Choose PET when the shopper has to see the product — clear and glossy is what PET is for. For home care the line is clear: bleach, alkalis and concentrated surfactants belong in polyethylene.

PP vs HDPE

PP takes heat better and can be run semi-translucent. HDPE is opaque and tough. If your product needs heat resistance or a semi-translucent look, choose PP; if it needs to hide what is inside and stand up to harsh chemicals, choose HDPE.

All three are blown in our own factory in Berrechid, Morocco: HDPE by extrusion blow moulding, PET by injection stretch blow moulding, and PP by blow moulding. The caps and pumps that go on them are supplied together with them.

    Questions

    Is HDPE or PET better for a shampoo bottle?

    Usually HDPE. HDPE is the usual body for shampoo and shower gel: it is opaque, tough and chemically resistant. Choose PET when the shopper needs to see the product, because PET is clear and glossy. If you need a semi-translucent look or heat resistance, PP is the third option.

    Can a PP bottle be clear?

    Semi-translucent, yes: PP can be run semi-translucent, and it takes heat better than HDPE. For a clear, glossy bottle that shows the product, choose PET. For an opaque bottle that hides what is inside and resists chemicals, choose HDPE. Tell us your product and we’ll recommend one.

    Which plastic for bleach or strong cleaners?

    HDPE. Bleach, alkalis and concentrated surfactants belong in polyethylene, and our HDPE bottle is opaque, tough and chemically resistant. It comes in 24/410, 28/410, 28/400 and 38/400, so it can take our dosing caps in 28/400 and 38/400 or a trigger sprayer in 28/400 or 28/410.

    Can you make bottles with recycled plastic?

    Yes. We run PP, PE, PS and PCR blends, so recycled content can go into the bottle. Tell us the PCR share you need and we’ll confirm it with your quote. The minimum order is 10,000 pcs, and the lead time is 7–25 days on an existing mould or 30–60 days on a new one.

    What is the clear double-wall jar made of?

    PETG, which resists impact, oils and actives. We make it as a thick-walled double-wall jar with a glass-like look; tell us the fill volume and we’ll quote the jar and lid together.
