Plastic and Your Baby: A Practical Guide for Australian Parents
Many new parents worry about plastics in baby feeding products. With so many bottles, storage containers and utensils made from plastic, it’s important to know which materials are safer and how to use them correctly. At Bubs n Grubs, we select feeding products that prioritise safety and quality so you can make informed choices with confidence.
Why plastic types (recycling codes) matter
Different plastics behave differently when heated, scratched or reused. As a simple rule of thumb:
- Use with care / avoid for heating: codes 3 (PVC), 6 (PS), 7 (OTHER – may include polycarbonate/BPA).
- Common safer choices for feeding gear: codes 2 (HDPE), 4 (LDPE), 5 (PP) – durable and typically BPA free.
Wear and tear (scratches, clouding) can increase the chance of chemicals migrating. Replace worn items and follow the product’s care instructions.
Are plastics safe for baby feeding in Australia?
Australian authorities continue to monitor food?contact plastics. Food Standards Australia New Zealand (FSANZ) – BPA overview reports that typical BPA exposure from food and packaging is low and within current health based guidance levels. Even so, many brands have shifted to BPA free materials (such as polypropylene) and parents often prefer to minimise heating plastics as an extra precaution.
Simple, evidence informed tips for everyday use
- Prefer polypropylene (code 5) or glass for bottles and storage where practical.
- Don’t microwave plastics unless the label explicitly states it’s suitable; avoid heating very fatty/sugary foods in plastic.
- Discard worn, cracked or cloudy items and replace teats/bottles per the manual.
- Hand wash or use top rack only if specified; avoid harsh abrasives that scratch surfaces.
- Store cool: let hot liquids cool slightly before transferring to plastic; avoid leaving plastics in hot cars.
Medela BPA Free Feeding Range (optimised for safety & convenience)
Medela bottles and breast pump kits are made from polypropylene (PP, recycle code 5) and are BPA free. PP is a light, semi cloudy plastic chosen for durability and cleanability. You’ll typically see a “5” and/or “PP” stamped on the base. For parents who want to minimise chemical exposure without sacrificing practicality, PP and glass are the most popular options.
- Why parents choose Medela PP bottles: BPA free construction, easy clean surfaces, compatibility with Medela pumps, reliable seals for storage.
- Good practice: replace bottles/teats when worn; follow the cleaning & sterilising instructions in the manual.

FAQs: Plastics, BPA and baby feeding
Is BPA banned in Australia?
There’s no mandatory ban. Baby bottles moved to BPA free materials via voluntary industry action, most current products are BPA free. FSANZ continues to monitor BPA and reports typical dietary exposure is low.
Which bottle materials are generally considered safer?
Glass and food grade stainless steel are solid choices. For plastics, polypropylene (code 5) and HDPE/LDPE (codes 2/4) are commonly used and BPA free.
Should I microwave baby food or milk in plastic?
Avoid heating in plastic unless the label specifically permits it. If you do, follow the manufacturer’s instructions exactly; otherwise heat in glass/ceramic and transfer once cooled slightly.
What do the recycling numbers mean?
They indicate the plastic resin type. For feeding gear, codes 2, 4 and 5 are common safer picks. Avoid heating items marked 3, 6 or 7 (7 may include polycarbonate which can contain BPA).
