PS sheet refers to a sheet made from Polystyrene (PS), which is a versatile thermoplastic polymer. PS sheets are widely used in various industries for their excellent clarity, rigidity, and ease of processing.
They are available in different forms, including solid sheets, foamed sheets, and embossed sheets, each with specific properties and applications. PS plastic sheet is a versatile thermoplastic material commonly used for thermoforming a wide variety of products. As a rigid yet impact-resistant solid plastic, it lends itself well to food packaging and laboratory equipment applications.
Thermoplastic Polymer

| Usage Temperature | -40℃ ~ 95℃ |
| Common Thickness | 200μm ~ 500μm |
PS sheets offer unique characteristics that make them ideal for various packaging and industrial applications.
Generates minimal static charge, making it suitable for packaging static-sensitive products.
Readily vacuum formable to create durable, impact-resistant shapes and containers through thermoforming.
Demonstrates excellent hygienic properties as it can be used in direct contact with foodstuffs without imparting harmful chemicals.
Easily colorable through the addition of pigments to produce materials in a wide array of hues for enhanced aesthetic appeal.
Exhibits high rigidity even at reduced thicknesses, allowing thermoforming of sturdy drinking vessels and other formed parts.
Meets environmental standards as its waste can be recycled or incinerated without releasing toxic emissions, supporting sustainability goals.
When combined with colorants, additives, or other polymers, polystyrene can be thermoformed into various products.
PS food containers and clamshell packaging are used for foods like hamburgers, sandwiches, salads, etc. to help keep food fresh and leak-proof. Its hardness and moldability make it well-suited for short-term use items.
Thin PS sheets can be cut, formed, and decorated for use in signage, displays, exhibition booths, and other promotional materials.
PS is used to make cast molds, orthopedic braces, medical device packaging, and other healthcare products.
PS sheets are often used to make protective packaging for electronics, appliances, fragile items, etc. due to their ability to cushion and protect items from damage. Expanded PS is commonly used to make packing peanuts.
Thermoforming packaging is a way to make custom plastic containers and trays.
Workers start with a flat sheet of plastic like polystyrene or polyethylene. They heat the plastic until it is soft and bendy. Then they use air or vacuum machines to push the warm plastic into shapes. The plastic cools down and gets hard in the new form.

PS (Polystyrene) Sheet is a packaging material known for its excellent clarity, stiffness, and heat resistance. Its main advantages include good transparency, dimensional stability, heat resistance (up to 100°C), and suitability for various packaging applications requiring clarity and heat resistance.
PS Sheet packaging is ideal for products requiring clarity, stiffness, and moderate heat resistance. Common applications include retort packaging, frozen foods, and products requiring transparent packaging with good dimensional stability.
PS Sheet offers good clarity and stiffness similar to PET, but with lower temperature resistance. It provides a cost-effective alternative to PET for applications not requiring high-temperature resistance, while maintaining good optical properties and dimensional stability.
PS Sheet can be used for retort applications with moderate temperature requirements (up to 100°C). For higher temperature retort applications, materials like RCPP or PET/HSPET are typically recommended for better heat resistance.
Common PS Sheet thicknesses include 200μm, 250μm, and 300μm. The selection depends on your specific application requirements, stiffness needs, and cost considerations. Thicker sheets provide enhanced stiffness and durability for demanding applications.
