The 100% Recyclable High Barrier Mono Material Trend

The development of Mono material recyclable packaging and dealuminated packaging will undoubtedly occupy the top spot in flexible packaging development in the coming years, without a doubt. As is well known, the difficulty lies in how to improve the barrier performance of a single material and the high barrier performance of dealumination. Many film companies are actively researching and developing various products and solutions in response to this.

Longdapac has successfully developed various high-performance VMPE aluminum plated films and VMCPP aluminum plated films with outstanding performance characteristics, forming a powerful product matrix covering both basic and high-end applications. Including: 1. Double sided corona enhanced aluminum plating for VMPE drug packaging. VMPE has excellent adhesion to the aluminum layer and corona discharge on the back of the PE substrate, solving the problem of insufficient peeling strength stability of the inner layer of solid particle pharmaceutical composite film. At the same time, its barrier performance meets industry requirements and is highly praised by drug packaging soft packaging enterprises.

Used for solvent-free composite of PE/VMPE rigid materials, with ultra-high strength (adhesion>12N), it successfully solves many problems such as white spots and aluminum plating transfer, providing assistance for color printing enterprises to research and deepen PET/VMPET solvent-free composite processes, and has been recognized by partners.

The most impressive achievement has arrived! Ultra high barrier series!

1. VMPE super strong aluminum plating and ultra-high barrier VMPE aluminum plating film: The adhesion of the aluminum layer is greater than 12N, and the dual indicators of oxygen and water resistance are both below 0.5, especially the typical value of water resistance index is within 0.2. The composite film structure barrier also fully meets the requirement of less than 0.5. It is the best choice for replacing aluminum foil with three-layer composite structure food and drug packaging in dry category, especially suitable for products with high moisture resistance requirements. It has been recognized by drug packaging customers and downstream pharmaceutical companies for mass production.

2. VMCPP’s super strong aluminum plating and ultra-high barrier VMCPP: aluminum layer adhesion>6N, oxygen resistance<15, water resistance<0.3, composite film water resistance performance is even below 0.1. It can not only meet the barrier requirements of OPP/VMCPP two-layer polyolefin material structure replacing the traditional OPP/VMPET/CPP three-layer structure composite film, but also has much better moisture resistance than the three-layer structure of VMPET high barrier aluminum plating film, especially suitable for product packaging with higher moisture resistance requirements and affecting taste. In addition, compared with the recently developed MDOPE/VMPE single material structure, it has significant advantages in material availability, comprehensive cost, and barrier performance.

3. VMCPP double-sided corona super strong aluminum coating and ultra-high barrier aluminum film: In addition to all the main properties of the super strong aluminum coating and ultra-high barrier VMCPP introduced above, it also has double-sided corona function, which can replace the coated high barrier VMOPP in the middle layer. The OPP/VMCPP/CPP single material structure replaces the OPP/VMPET/PE structure, and the composite structure has outstanding barrier performance, with oxygen resistance<3 and water resistance less than 0.1, but its price is only about half of the coated VMOPP, providing more choices for flexible packaging customers and offering a cost-effective solution for the development of single materials in the industry.
