Product Overview

BOPS (Biaxially Oriented Polystyrene) sheet is a high-performance rigid thermoplastic material manufactured by heating polystyrene resin to a flexible state and conducting professional longitudinal and transverse biaxial stretching treatment. This precise biaxial orientation process optimizes the molecular structure of the material, endowing BOPS sheet with superior comprehensive physical and chemical properties compared with ordinary PS sheets. As an eco-friendly, cost-effective and versatile packaging material, BOPS sheet features high transparency, excellent rigidity, stable dimensional performance and safe food-grade characteristics, which is widely recognized and applied in global packaging and thermoforming industries.

Core Product Features

Ultra-high Transparency & Gloss: The sheet boasts crystal-clear clarity and smooth surface with high glossiness, without impurities, fog or yellowing. It can perfectly display the appearance of packaged products, greatly improving product grade and display effect, which is ideal for high-end transparent packaging.
Excellent Mechanical Properties: Professional biaxial stretching technology enhances the material’s tensile strength, stiffness and toughness. The sheet is rigid and not easy to deform, crack or wrinkle during processing, transportation and use, with strong structural stability.
Superior Dimensional Stability: BOPS sheet has low shrinkage rate and stable physical properties under normal temperature and processing conditions. It can maintain precise size and flatness during thermoforming, cutting and printing, ensuring high consistency of finished products.
Food-grade Safety & Hygiene: The raw materials comply with international food contact safety standards. The sheet is non-toxic, odorless, harmless and free of harmful additives. It has good oil resistance and low-temperature resistance, suitable for direct contact with various foods.
