Mono-material High Barrier PP Retort Pouch is Now Available in China

1) Mono-material flexible packaging marketing today

According to the analysis of the market data forecast report, the European flexible packaging Market will grow from US $28.22 billion in 2021 to US $41 billion by the end of 2026, with a compound annual growth rate of 7.76%. In addition, CEFLEX statistics show that more than 40% of food in Europe uses flexible packaging, and 10% of all consumer packaging materials are used.


Flexible packaging is the main force in the packaging industry. The amount of plastic waste generated by soft packaging after consumption is naturally huge, and the recovery difficulty is high and the value is low. As a single material package that is often listed in the “hot search list” of plastic circular economy, because it can greatly improve the recycling value of packaging, it is still very attractive, and the demand is growing stronger, becoming one of the ways for more and more brands and packaging suppliers to establish a brand concept of sustainable development.


The biggest technical difficulty of mono material packaging is heat resistance and barrier. At present, the industry is solving the heat resistance problem of single material packaging bag making through the improvement of raw material resin performance and processing technology

2) RetortPouch from Mondi

Mondi, the world’s advanced packaging manufacturer, launched RetretTouch recyclable single material cooking packaging, which is applied to a series of food and wet pet food.


Generally speaking, moist or semi moist foods are heat treated in steam or hot water distillation packaging containers to achieve sterilization, so these foods need to be cooked and packaged.


These packages use aluminum foil as a barrier layer, which is difficult to recycle. Mondi has developed an innovative high barrier film to replace aluminum foil, which can maintain high temperature during distillation and achieve shorter processing time. The new single material cooking packaging is completely recyclable, providing a special shelf life for single material packaging solutions, and reducing potential food waste.


Mondi spent more than two years researching and testing the product to ensure that it meets important application requirements. As part of its commitment to sustainable development, the launch of RetortTouch recyclable products is another step towards Mondi’s goals.


At the beginning of 2021, Mondi created three sustainable packaging for the new vegetarian product line of food manufacturer Orkla. It is mainly used in Orkla’s corn cakes, corn chips and corn roll flavoring products.


Corncake is Mondi’s first food packaging to adopt its “BarrierPack Recyclable” solution. The package is made of a single material with high barrier property and light weight. The sealed adhesive tape can keep the freshness of food and extend the shelf life.


In order to maintain the crispness and fresh taste of corn chips, Mondi uses metal free high resistance laminate, which makes the new packaging solution completely recyclable. This package also avoids the leakage of grease inside.

3) Mono-material high barrier PP retort pouch manufacturing in China

Wanshun New Material Group Co., Ltd., founded in 1998, is a national high-tech enterprise integrating environmental protection packaging materials, high-precision aluminum foil and functional film.

At the beginning of the business, the company, based on the national policy guidance, seized the opportunity of the country’s strong support for the environmental protection packaging industry, took the market as the guidance, took scientific and technological innovation as the driving force, worked hard and made progress, and gradually developed into a leading enterprise in the domestic packaging material industry.

Since the company landed on the GEM, it has adjusted its development strategy by leveraging the capital platform, and established a diversified development strategy with medium and high-end packaging materials, aluminum foil packaging business, and functional films as the “troika”.

The high barrier PP retort film will make the 100% recyclable high barrier mono-material PP retort pouch available for us.

So we have high barrier Mono-material PE pouch ( made of MDO-PE / PE and high barrier mono-material PP pouch now. 

4) Technical advantages

At present, PVA coated barrier and EVOH barrier are widely used in single environmental protection structure. For some dry food and daily chemical products, the water and oxygen resistance are basically comparable to traditional multi material packaging, but the shelf life of food is shorter than that of conventional composite packaging, and the cost is more than 20%~30% higher than that of ordinary packaging.


However, the barrier effect of single structure soft bag is still limited for oil blocking, light blocking, chemical resistance and other issues, so it is difficult to be widely used in all food packaging at present.


Nevertheless, food and beverage brands and packaging enterprises are very enthusiastic about developing single materials, and constantly break through the technical bottleneck of single materials. It is believed that under the “double carbon” goal and sustainable development, single material packaging will be widely used in the future.
