Longdapac is launch the 100% recyclable mono-material PCR PE pouches. This new product combine with PCR PE materials and mono-material PE concept to make it with both 100% recyclable and PCR comparable.
Longdapac had spent 3 years in developing 100% recyclable retort pouches, not the mono-material PP retort pouch is mature and good quality. It can be with high barrier, and the detail film structure is BOPP/High barrier PP/RCPP.
In this article, we mainly talk about 3 key factors of making 100% recyclable retort pouch.
Longdapac is one of the leading manufacturers in 100% recyclable mono-material PE laminated roll stock film products. After couple years R&D from Longdapac engineers, now we can supply same good quality as conventional material. This is getting good reputation in our customers.
To make quality 100% recyclable Mono-material PE Pouches with zip Lock, the outer layer PE should be higher temperature, while the inner PE should be with low temperature, and it is also very important to have low temperature PE zip lock.
Longdapac engineers are doing sufficient Research & Development on the lamination of mono-material film. So the quality is very good now.
Longdapac started to make high barrier MDOPE from 2020, and now the new technology makes the high barrier MDOPE mature. Currently we have already provide high barrier MDOPE for billions of pouches.
White spots often occur in solventless lamination process. After a large amount of practical experience accumulation and multiple discussions and summaries by industry professionals, we have largely controlled this problem in practical operation. However, there are differences in product types, materials used, and processes among each enterprise, and the reasons for white spot problems are also different. To comprehensively understand and effectively solve such problems, and to maximize the control of solvent-free composite white spots, let’s summarize and analyze the control and response measures for operational problems.
Today we will talk about 12 reasons which might cause white spots in solventless lamination.
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.
An innovative recyclable PE Mono material structure Stand up Pouch was launched in Longdapac won the China Packaging Award for Sustainable Development on September 13, 2023.
Longdapac is promoting the sustainable development of PA Film. The company has developed PA Film made from 100% post consumer recycled (PCR) materials. These materials complement Longdapac’s 100% post industrial recycled (PIR) grade PA, which has been on the market since 2021.
