Cosmo Films launches anti-fog transparent BOPET lidding films

Cosmo Films has launched its sealable, peelable transparent anti-fog BOPET (PET) lidding film, engineered to enhance product visibility, extend shelf life and improve packaging performance across refrigerated and fresh food categories.
 
Condensation remains a key challenge in food packaging, especially in cold-chain environments where temperature variations lead to moisture build-up inside packs. This fog formation can obscure the product’s appearance and impact consumer perception at the point of sale. Cosmo Films’ new anti-fog PET lidding film incorporates a coating on the sealable side that delivers cold anti-fogging effect, preventing droplet formation and maintaining consistent clarity throughout storage and display.
 
Designed for performance and versatility, the film offers low sealing temperature, ensuring compatibility with high-speed packaging lines while optimizing energy efficiency. It is sealable and peelable, enabling strong yet easy-open seals without compromising pack integrity. The film is microwaveable, adding convenience for ready-to-eat and prepared food applications. Importantly, it enhances shelf life by 4–5 days for fresh salads and vegetables by helping maintain internal pack conditions. The lidding film is compatible with a wide range of substrates, including PP, HIPS, PET (APET, CPET), PVC and LDPE containers, making it suitable for diverse packaging formats. In line with sustainability goals, the film is recyclable in the mainstream recycling stream when used with PET trays.
 
Kulbhushan Malik, global business head, Cosmo Films, said: 'In food packaging, visibility is directly linked to consumer trust and purchase decisions. With our anti-fog transparent BOPET lidding films, we are addressing a key pain point for brands by combining condensation control with superior clarity, strong sealing performance and ease of use. This launch reinforces our commitment to expanding our specialty portfolio with high-performance, value-added solutions that support both product protection and brand differentiation.'
 
The new lidding films are suitable for a wide range of applications, such as refrigerated and frozen foods, prepared fruits, fresh-cut vegetables, ready-to-eat meals, bakery items, dairy products including yogurt and butter, pasta, fresh meat and salami. It also performs effectively in fresh produce packaging for vegetables, herbs, berries, fruits and mushrooms – categories where clear visibility and freshness perception are critical to purchase decisions.
