How PET & PLA Cups Are Made – Inside Xiamen Xiefa Plastic Packaging Factory

In today’s food and beverage industry, disposable drink cups play an essential role in serving coffee, bubble tea, smoothies, and juices. At Xiamen Xiefa Plastic Packaging Co., Ltd., we specialize in manufacturing high-quality PET and PLA cups, offering sustainable solutions for businesses worldwide. Let’s take a closer look at how these cups are produced and why they are a smart choice for your brand.

PET Cups Production – Clarity and Strength

PET (Polyethylene Terephthalate) is widely used in drink cups because of its crystal-clear transparency, strength, and recyclability. At Xiefa factory, the production process follows strict quality control:

1. Raw Material Preparation – Food-grade PET resin is selected to ensure safety and purity.

2. Extrusion & Sheet Forming – PET resin is melted and processed into uniform sheets.

3. Thermoforming – Using advanced molding machines, PET sheets are shaped into cups of different sizes.

4. Trimming & Quality Check – Each cup is precisely cut, then inspected for clarity, thickness, and durability.

The result is a strong, transparent, and recyclable cup that enhances the presentation of any beverage.

PLA Cups Production – Plant-Based and Biodegradable

PLA (Polylactic Acid) is made from renewable resources such as corn starch or sugarcane. Unlike traditional plastics, PLA is biodegradable and compostable under industrial conditions, making it an excellent eco-friendly option.

The production steps include:

1. Biopolymer Pellets – Plant-based PLA resin is sourced from certified suppliers.

2. Sheet Extrusion – PLA pellets are melted into sheets with controlled temperature to maintain stability.

3. Molding – Sheets are thermoformed into cups, similar to PET production.

4. Inspection & Packaging – Each PLA cup is tested to ensure it meets food-grade safety and eco-friendly standards.

PLA cups are clear, sturdy, and sustainable, ideal for brands that want to reduce their environmental footprint.
