What is Lidding Film? A Flexible Packaging Guide By Stanley

Lidding Film has become one of the indispensable materials in the packaging of food, personal care and daily chemical products. It not only relates to the sealing property, safety and freshness of the product, but also directly affects the consumer experience and professional image of the brand. For enterprises that want to improve packaging efficiency and quality, learning about the basic principles and technical trends of lidding film is necessary.

As a professional flexible packaging manufacturer, Stanley Package has been deeply engaged in the research and development and customization of Lidding Film for many years. This article will take you to systematically understand the structure, function, type and industry application of lidding film.

Basic Definition of Lidding Film

Lidding film is a heat-sealing film material used to seal the orifice of plastic trays, bowls, cups or other containers. It is sealed hermetically to the rim of the container through heat sealing or cold sealing technology to form an enclosed environment, to keep the contents from the influence of the outside world, and to facilitate transportation, storage and selling.

In the packaging structure, lidding film is generally an overlying cover film, which is paired with the bottom rigid tray to form a complete packaging unit. Its advent has greatly improved the function, visional expression and industrial automation level of packaging.

Main Functions of Lidding Film

A high-performance lidding film is far more than just “covering” the product. It often integrates the following functions:

High-efficiency sealing performance

The lid film can prevent external pollutants such as air, moisture, dust, and microorganisms from entering the interior of the package, thereby extending the shelf life and ensuring the freshness and safety of the product.

Good tearability

Consumer experience is an important part of product design. The lid film can be customized as “easy to tear” according to customer needs, which is easy to tear by hand and can be opened smoothly without the help of tools.

Excellent printing effect

Through surface or middle layer printing, the lid film can present high-quality patterns, brand LOGO and instructions, improving the product appearance and shelf appeal.

High barrier performance

Some products have special requirements for gas, water vapor, UV or odor barrier. Stanley Package provides high barrier solutions such as EVOH, aluminum foil, and multi-layer co-extrusion film.

Anti-fog and anti-oil performance

When used for refrigerated food or oil products, the lidding film needs to have anti-fog and anti-oil functions to maintain a clear display effect and not affect consumer choice.

Automatic packaging adaptability

Stanley lidding film supports high-speed automatic sealing equipment, with firm and efficient sealing, suitable for industrial mass production.
