Innovative application of sealing film in the daily necessities industry

Large Middle Small Source:Leadtra Packaging View:- Date:2025-07-03 14:11:27

Sealing innovation of mouthwash packaging

The mouthwash sealing film adopts a triple protection design, which combines high barrier properties and easy opening characteristics. The inner layer is made of PE/PP composite material that is resistant to alcohol corrosion, effectively resisting erosion with up to 20% alcohol content; The middle aluminum foil barrier layer ensures that volatile components such as menthol are not lost; The outer heat sealing layer perfectly fits the HDPE bottle mouth, achieving no water leakage. The innovative "one touch open" design is achieved through laser pre cutting, which not only meets the requirements of child safety packaging, but also facilitates one handed operation for adults. Some high-end products also integrate a usage reminder ring, which intuitively displays the recommended usage amount through color changes.

Breakthrough application of breathable membrane technology

In products such as activated carbon packs and dehumidifiers, microporous breathable sealing films exhibit excellent performance balance. Its precise microporous structure with 500-800 pores per square centimeter allows air to exchange at a rate of 0.5-1.2L/min/m2 while completely blocking dust leakage. The new PTFE breathable film breaks through tradition and achieves precise pore size control of 0.01 μ m in the packaging of aromatic wax sheets, ensuring slow release of aromatic molecules while avoiding oxidation and deterioration of wax sheets. The breathability of this type of film material can be precisely adjusted through lamination process to meet different volatilization rate requirements.

Intelligent sealing solution for aromatherapy products

The sealing film of aromatherapy bottles is undergoing a transformation from simple sealing to functional integration. ① Essential oil products adopt a double-layer film structure: the inner layer of fluorinated film resists the corrosion of essential oils, and the outer layer of aluminum foil maintains fragrance; ② Non fire aromatherapy uses a selective permeable membrane to precisely control the volatilization rate by changing the thickness of the PE film (50-200 μ m); ③ Innovative temperature controlled aromatherapy sealing film, built-in paraffin microcapsules, automatically adjusts the opening and closing of the ventilation holes according to the ambient temperature, maintaining a constant release of fragrance. Some luxury brands have also launched magnetic sealing films that can be repeatedly sealed, achieving thousands of opening and closing without losing sealing properties through magnetic suction structures.

The future trend of technological integration

The latest developed "breathing" intelligent sealing film is disrupting traditional design. The aromatherapy sealing film manufactured using MEMS microelectromechanical technology can automatically adjust the air permeability according to the environmental humidity; The pH responsive membrane applied to mouthwash changes its porosity when in contact with liquid, controlling the rate of fluoride release. These innovations not only enhance product efficacy, but also create differentiated competitive advantages through patented sealing solutions, driving daily necessities packaging into a new era of functional intelligence.

Leadtra aluminum foil sealing film has introduced foreign composite equipment and technology to ensure tight and smooth sealing with easy tearing effect. It has an exquisite appearance, tight sealing, green safety, and is widely used for sealing products such as food, cosmetics, daily necessities, medical supplies, etc. If you are interested in or have any questions about us, please feel free to consult.
