Factors like decontamination and filling possibility have to be considered when designing the perfect bottle shape and selection of the raw materials to be used. Various synthetic bottling materials are used in the food industry.

Dairy products are light sensitive. A three-layer (anti-UV) HDPE bottle suits long-life dairy products best.
Vitamin-enriched dairy products, clinical and pharmaceutical products can be filled in six-layer (anti-UV and anti-O2) EVOH bottles.
HDPE is especially suited for dry decontamination at high temperatures. SF&DS’s flexible and user-friendly blowmoulders are renowned for producing quality mono-, three-layer and six-layer HDPE bottles.

For long-life fruit juices the advantages of PET are many .
The juice remains clearly visible;
PET is less oxygen-sensitive than PE and thus well suited for aseptic filling with fruit juices, as they are less UV-sensitive, but more oxygen-sensitive;
Lightweight PET bottles help to save on packaging costs;
Extensive testing proved: SF&DS’s Asep-Tec decontamination methods suit the processing of various PET containers perfectly.

Besides PET and HDPE, fruit juice producers may choose for PP for its contact clarity, allowing good visibility of the bottle contents. PP however is less clear and also more O2‑sensitive than PET. PP bottles can be blown on the SF&DS Blowmoulder and filled on the Asep-Tec, using dry-decontamination.

The SF&DS Blowmoulder produces bottles in every possible shape. After changing moulds the Blowmoulder can be easily switched over to other bottle shapes.
