1. Crystal-Clear Transparency
PET offers near-glass clarity. This allows customers to see the actual color and texture of your product (e.g., a rose-gold serum or a green clay mask), building trust and reducing the need for “window box” packaging.
2. Lightweight & Unbreakable
Unlike glass, PET jars are shatterproof. This reduces shipping costs, minimizes warehouse breakage risks, and enhances safety for bathroom use.
3. Eco-Friendly Credentials
PET is one of the most recyclable plastics globally. Advanced options now include:
Plant-based PET (bio-PET)
Chemically recycled PET (PCR ——Post-Consumer Recycled)
4. Chemical Resistance
PET provides excellent resistance to oils, alcohols, and mild acids, making it suitable for formulations containing active ingredients like salicylic acid or essential oils.
Color Options: Transparent, solid custom PMS colors, pearlescent, or gradient effects.
The Secret to Freshness: Sealing & Sustainability
Preserving the formula is non-negotiable. PET injection jars typically pair with PP (Polypropylene) or PE (Polyethylene) lids and include an inner liner or induction seal to block oxygen and prevent leakage.
