What is a Thermoformed Plastic Food Container?

Introduction

As a manufacturer specializing in plastic food packaging, we are often asked what exactly a thermoformed plastic food container is, and why it has become so widely used in today's takeaway and food service industry. In this article, we will explain the concept in simple terms, the materials we use, and how businesses can benefit from choosing the right thermoformed packaging solution.

Thermoforming is a widely used manufacturing process in the food packaging industry. It involves heating a sheet of plastic until it becomes flexible, then forming it into a specific shape using molds, and finally trimming it to create the finished product. These containers, which include thin-gauge items like blister packs, clamshells, and shallow trays for food display. They can safely hold hot meals, cold salads, fresh fruits, or bakery products.
At our factory, the two main materials we work with are:
• PP (Polypropylene): Known for its heat resistance and microwave safety, PP containers are best for hot meals and reheatable takeaway dishes.
• PET (Polyethylene Terephthalate): PET containers are crystal clear, making food look fresh and appealing. They are resistant to oil and moisture, and also also recyclable, which is why many salad, dessert, and cold food packaging solutions are made from PET.

Tips to Choose the Right Thermoformed Food Containers

• The Material: PP containers are heat-resistant and microwave safe, while PET containers offer better clarity and moisture resistance.
