For thermoformers producing food trays and containers, polypropylene (PP) is a popular choice—yet it often presents significant challenges, such as a narrow processing window, sheet sagging, uneven wall thickness, surface defects, and potential food safety risks stemming from raw material contamination or an unclean production environment. Poor sheet quality not only leads to higher scrap rates and frequent downtime for machine adjustments but can also result in costly non-compliance with regulatory standards.

With over 20 years of experience as a manufacturer of plastic sheets—including PP, PET, HIPS, and PP synthetic paper—we offer food-grade PP sheets specifically engineered for thermoforming and vacuum forming applications. Our products are ideally suited for the production of various food trays and containers. Key advantages include:

1. Production in Food-Grade Cleanrooms

Our PP sheets intended for food-contact applications are extruded within dust-free cleanroom environments. The entire process—from raw material feeding and extrusion to winding—takes place in a fully enclosed system, effectively eliminating the risk of contamination from dust or microorganisms. We use only food-contact-grade virgin resin, with no inclusion of recycled materials of unknown origin, ensuring full compliance with food packaging safety standards.

2. Custom Formulations Optimized for Thermoforming and Vacuum Forming

PP material is prone to sagging and wall-thinning when heated. Our modified PP sheets feature superior melt strength, delivering excellent performance in deep-draw forming. They ensure uniform wall thickness and crisp, well-defined structural details. This reduces the need for machine fine-tuning and significantly lowers scrap rates on thermoforming production lines. The finished trays are suitable for both refrigeration and microwave heating, making them an ideal packaging solution for ready-to-eat meals, meat products, and fresh food.

3. Consistent Batch Quality and Reliable Lead Times

Drawing on over two decades of expertise in extrusion technology, we guarantee consistent thickness, flatness, and surface finish across every production batch. We offer customization for thickness, width, and color. We can provide samples for testing and are fully equipped to handle large-scale production, ensuring stable delivery even during peak seasons.

4. Extensive Product Portfolio

In addition to food-grade PP sheets, we have developed a new high-barrier PP/EVOH sheet. Leveraging the exceptional oxygen-barrier properties of EVOH, this material effectively prevents oxygen from entering the packaging, significantly slowing down oxidation and spoilage. This extends the shelf life of fresh produce, ready-to-eat meals, and meat products. These sheets are compatible with vacuum-forming and thermoforming processes, allowing for the direct production of high-barrier food trays and containers. Clients can upgrade their packaging—reducing food waste and expanding opportunities for long-shelf-life product orders—without needing to replace their existing thermoforming production lines. We also supply PET, HIPS, and PP synthetic paper, serving as a one-stop source for all your material sampling and mass production needs across various packaging projects.

The quality of thermoformed food packaging begins with the choice of plastic sheet. Don’t let inconsistent sheet quality hinder your production efficiency or force you to waste valuable time addressing defects.
