Breaking through the co extrusion boundary! Koes Chemical's new generation of adhesives leads the innovation of multi-layer co extruded films

In today's world where food packaging pursues "180 day freshness lock", pharmaceutical packaging strictly adheres to "sterile standards", and electronic packaging urgently needs "anti-static black technology", the performance upgrade of multi-layer co extruded film has become a core proposition in the global flexible packaging industry. Koes Chemical has accurately identified market pain points and launched CF420 multi-layer co extrusion special adhesive, which uses revolutionary technology to solve the three major difficulties in the industry and redefine the bonding standards for co extrusion films.

1、 Market dilemma: the "triple shackles" of traditional adhesives
1. Performance ceiling

Traditional adhesives are prone to delamination and brittleness in high-temperature steaming (>121 ℃) or low-temperature cold chain (-20 ℃) environments. A food company has reported that the peel strength of a certain brand of adhesive used in PET/PE co extruded film has decreased by 40% after a 3-month shelf life, directly leading to product recall risk.

1. Environmental compliance pressure

The strict restrictions on heavy metals and VOCs imposed by the EU REACH regulation and the Chinese GB 9685 standard have led to a crisis of phasing out solvent based adhesives. According to industry data, 15% of domestic flexible packaging companies have been forced to shut down in 2024 due to substandard adhesive environmental protection.

1. Game of Cost and Efficiency

Traditional techniques require additional coating processes, resulting in an increase of 800-1200 yuan per ton of film production cost and a 20% decrease in production efficiency. A certain daily chemical packaging enterprise estimates that if it switches to co extrusion technology, it can save up to 3 million yuan in annual costs.

2、 Koes Breaks: CF420's' Four Major Disruptive Breakthroughs'
1. Molecular level adhesion to overcome high barrier barriers
CF420 adopts nano crosslinking technology to achieve a 12N/15mm peel strength (ASTM D903 standard) in PA/EVOH/PE co extruded structure, which is three times higher than traditional products. Experimental data shows that the oxygen permeability of the 7-layer co extruded film using this adhesive is as low as 0.08cc/(m ² · 24h · atm), fully meeting the ultimate requirements for high barrier properties in pharmaceutical blister packaging.

2. Wide temperature range stability, suitable for all scene requirements

High temperature tolerance: Maintain stable performance for 180 days in a 135 ℃ cooking environment, solving the problem of "bulging" in pre packaged vegetables.

Low temperature toughness: Peel strength attenuation of less than 5% under -40 ℃ freezing environment, providing long-term protection for ice cream packaging.

Chemical corrosion resistance: FDA certified, capable of withstanding the corrosion of oils, fats, acidic and alkaline media, and performing outstandingly in the field of seasoning packaging.

3. Environmental pioneer, ushering in the era of green co extrusion

Solvent free formula: VOC emissions are approaching zero, certified by UL ECOLOGO, helping customers pass EU food contact material testing.

Bio based innovation: using 30% renewable castor oil raw materials, the bio carbon content reaches the industry-leading 45%, which is in line with the "dual carbon" policy orientation.

4. Technological Revolution, Reshaping the Benchmark of Production Efficiency

Co extrusion integration: directly participating in multi-layer co extrusion casting/blow molding processes, eliminating the coating process, and reducing comprehensive costs by 15% -20%.

Rapid extrusion: The melt viscosity is reduced by 30% compared to traditional products, and it is compatible with high-end equipment such as Windm ö ller&H ö lscher from Germany and Mitsubishi Heavy Industries from Japan, increasing production capacity by 25%.

3、 Benchmark case: The leap from laboratory to production line

1. Food packaging field
A leading dairy company uses CF420 to produce 7-layer co extruded film, extending the shelf life of yogurt cups from 45 days to 90 days. At the same time, packaging costs are reduced by 12% due to the absence of aluminum foil layers. This case has been selected for the 2024 "China Food Packaging Innovation White Paper".

2. Pharmaceutical packaging field

A listed company uses CF420 to produce PA/PE co extruded film, which has successfully passed the verification of gamma ray sterilization. It has achieved a 72 hour adhesion force of>4.5N/25mm in the packaging of retention needles, and the customer complaint rate has decreased by 70%.

3. Electronic packaging field

In response to the demand for aluminum-plastic film for mobile phone lithium batteries, CF420 has undergone special anti-static modification to reduce the surface resistance of the co extruded film to below 10 ΩΩ, perfectly matching the production standards of dust-free workshops.

4、 Industry experts recommend: the 'barometer' of technology trends
The launch of CF420 marks a qualitative change in multi-layer co extrusion technology from 'functional realization' to 'performance surpassing'. ”The director of the Expert Committee of the China Packaging Federation said, "Its molecular level bonding technology and wide temperature stability will promote the upgrading of packaging in high value-added fields such as food and medicine

5、 Seizing the initiative: Koes' "Three Empowerment Plans"
