Eisai Breathable Film

Breathable films for hygiene materials allow a degree of gas transmission, usually allowing air to pass through normally, while still maintaining barrier properties against liquids and other contaminants. These films are commonly used in products such as diapers, feminine hygiene products, and incontinence aids, which require a balance between protection from fluids and comfort through ventilation.

The following are some of the key features and considerations associated with breathable films for hygiene materials.

1. Material Breathable membranes are typically made from microporous materials or include laminates with varying porosities. These films can incorporate polymers such as polyethylene, polypropylene, or specialized materials such as polytetrafluoroethylene (PTFE) to create micro-sized pores that allow air to pass through but block liquids.
2. Breathability: The breathability of a film is measured by its gas transmission rate (GTR), which indicates how much air can pass through the film in a given area and time. This property is critical to maintaining user comfort.
3. Liquid Barrier: Although breathable, the film should provide an effective liquid barrier to prevent leakage and maintain hygiene.
4. Strength and Durability: The film should be strong enough to withstand abrasion during handling, transportation and use without compromising its breathability or barrier properties.
5. Soft and comfortable: For direct contact with the skin, the film should be soft and comfortable, sometimes achieved through the use of non-woven or soft polymer films.
6. Environmental considerations: As with other types of packaging, there is a growing emphasis on the use of environmentally friendly materials and methods of producing breathable films. This includes consideration of the recyclability of the materials used and the reduction of waste in the manufacturing process.
7. Cost: Due to the complexity of the materials and manufacturing processes involved, the cost of breathable films can be higher than traditional non-breathable films.
8. Application Methods: Breathable films can be applied to hygienic products through a variety of methods, including thermal bonding, ultrasonic welding or adhesives, to ensure a strong and reliable attachment to the product.
9. Regulations: Materials used in hygiene products, including breathable films, may be subject to specific regulations regarding safety, environmental impact and labeling requirements.
10. Consumer Preferences: The hygiene products market is increasingly focused on consumer preferences for comfort, performance and sustainability, which is influencing the development of breathable films and packaging solutions.

Breathable films for hygiene materials play a key role in balancing protection and comfort, contributing to the overall quality and user experience of the hygiene products they package.

These films are mainly produced using cast film lines.
