PET (Polyethylene Terephthalate) is a preferred material in the plastic packaging industry due to its transparency, strength, and recyclability. Two main methods, vacuum forming and thermoforming, are commonly used to manufacture PET cups, each with distinct principles, product attributes, and application areas. Vacuum forming is cost-effective and suitable for lightweight, everyday cups, while thermoforming ensures high-quality, durable products for premium use cases. This article breaks down the features of both techniques, offering insights into their strengths and practical applications.
