Product Features
Mono Material Flexible Packaging is designed to reduce the complexity of conventional multi-material structures while maintaining the functionality required for product protection, filling, transportation and storage. Sunkey provides PE- and PP-based solutions for different flexible packaging applications.
ono-Material Structure
Our single material packaging solutions primarily use materials from the same polymer family, such as PE-based or PP-based structures, helping simplify material composition and support recycling-oriented packaging design.
Mono PE & Mono PP Options
Different material systems are available according to product requirements, including Mono PE Packaging and Mono PP Packaging. The appropriate structure can be selected according to sealing, stiffness, strength, processing and end-use requirements.
Custom Barrier Performance
Barrier properties can be customized according to the packed product. Recyclable mono material packaging solutions can be developed for different oxygen, moisture and aroma protection requirements.
Multiple Packaging Formats
Mono-material structures can be converted into stand-up pouches, flat pouches, rollstock films and other flexible packaging formats according to filling and application requirements.
Custom Printing
High-quality custom printing is available for logos, brand colors, product graphics and technical information, helping maintain professional brand presentation while transitioning toward mono-material structures.
Applications
Our mono material flexible packaging solutions can be customized for a wide range of food and non-food applications.
Snacks & Nuts
Suitable for products requiring moisture protection, lightweight packaging and high-quality printed presentation.
Pet Food & Pet Treats
Custom structures can be developed according to strength, sealing and barrier requirements for dry pet food and treats.
Frozen Food
PE-based recyclable flexible packaging can be designed according to low-temperature resistance, toughness and sealing requirements.
Coffee & Dry Foods
High-barrier mono-material structures can be developed for products requiring enhanced oxygen, moisture or aroma protection.
Powders & Granules
Suitable for various dry food, powder and granular products requiring flexible packaging.
Household & Personal Care Products
Single material packaging can also be customized for selected household, personal care and other non-food applications.
Advantages Supports Recyclability-Oriented Packaging Design
Compared with many conventional laminates combining different polymer families, recyclable mono material packaging simplifies material composition and can improve compatibility with appropriate recycling streams.
Actual recyclability depends on the complete packaging structure and the collection, sorting and recycling infrastructure of the target market.
PE & PP Material Solutions
Different products require different packaging performance. Sunkey can develop PE- or PP-based structures according to the required flexibility, stiffness, heat resistance, sealing and processing performance.
High Barrier Options
Moving toward mono-material packaging does not mean product protection should be ignored. High-barrier solutions can be developed according to oxygen, moisture, aroma and shelf-life requirements.
Multiple Pouch Formats
Our recyclable flexible packaging can be customized into stand-up pouches, flat pouches, rollstock films and other packaging formats according to product and filling requirements.
Recycle-Ready Packaging Development
Recycle ready packaging can be developed with consideration for material selection, barrier technology, inks, adhesives, closures and other packaging components according to applicable target-market guidelines.
Customized Packaging Solutions
Material structure, barrier performance, size, pouch type, printing and functional features can be customized according to your product, filling equipment, shelf life, transportation conditions and target market.
