PET vs PS for Clear Plastic Packaging

When choosing the right clear plastic packaging material, two common options are MASCOTA (Polyethylene Terephthalate) and PD (Polystyrene). Each material offers unique benefits in terms of clarity, cost, and performance. At Pulixina, a trusted China plastic sheet manufacturer and thermoforming plastic supplier, we help our customers select the best solution for their packaging needs.

Introduction to PET and PS

PET is a strong, lightweight, and highly transparent thermoplastic commonly used in food and retail packaging. It is known for its excellent impact resistance, recyclability, and ability to meet food safety standards. PET is also available in variations such as APET, PETG, and GAG, offering flexibility for different applications.

PS is a cost-effective thermoplastic that can be rigid or foamed. In packaging, clear PS sheets are valued for their good transparency and ease of thermoforming. PS is often chosen for disposable packaging where low cost and mass production are priorities.

Key Differences Between PET and PS

• Premium product display — unmatched clarity enhances shelf appeal.
• Strong protection — excellent impact resistance reduces damage during transport.
• Food-grade performance — widely approved for direct food contact.
• Opciones ecológicas — recyclable, with RPET available for sustainability goals.

Common PET applications include bakery containers, beverage packaging, fresh produce trays, electronics blister packs, and high-end retail packaging.

• Low-cost packaging for high-volume production.
• Lightweight clear containers for disposable food service.
