Food-Grade Plastic Packaging Materials: PET vs HDPE vs PP
- When sourcing plastic packaging for food and nutraceutical products, many buyers get confused among PET, HDPE and PP materials. Each plastic resin has unique features that directly affect product shelf life, safety and market compliance.
- At Brotherpack, our five core packaging lines — protein powder jars, vitamin capsule bottles, gummy & snack containers, sauce bottles and custom molded food jars — use these three mainstream food-safe plastics.
Clear PET is widely used for gummies, candies and visible retail products, featuring low cost and good transparency.
HDPE offers excellent moisture and light barrier performance, perfect for protein powder and dry nutritional supplements that need long-term storage.
PP is heat-resistant, suitable for hot-filled sauces and food items requiring high-temperature processing.
All raw materials are food-contact certified, and production is completed inside our 100,000-class clean workshop to meet FDA and EU regulations. We support customized capacity, color, cap types, silk-screen printing and private labeling for bulk orders. Our team can recommend the most suitable plastic material based on your product formula, storage environment and target market requirements.- If you are unsure which material fits your packaging project, feel free to send us your product details for a free professional consultation.
