Green Innovations Plastic Solution more Sustainable than Paper

RKW will be highlighting five key benefits that the RKW Pro Vent Ecore 5 self-venting plastic sack offers over paper sacks in terms of sustainability. The solution will be showcased at this year's Powtech event which is scheduled to be held from April 9-11 in Nuremberg. The self-venting plastic sack is fully recyclable, means less packaging, it offers reliable product protection, maximum moisture barrier – and enables a clean filling process. Made from 100 % recyclable polyethylene, this stable packaging solution for powdery, moisture-sensitive goods has been compliant with the 2020 EU standards for more than ten years.

When it comes to investment decisions, the sustainability of a technology plays a crucial role. The question of material continues to dominate the packaging debate. While paper is regarded as a ‘natural’ material in the eyes of the public, plastics increasingly suffer from the image that they are unsustainable. But in reality, plastic packaging is often a more effective and sustainable alternative to conventional paper packaging – especially in terms of recycling, material savings, product protection, moisture barriers, and the entire process chain.

100 % recyclable

The RKW Pro Vent Ecore 5 plastic sack solution presented under a new name at Powtech is an outstanding example of sustainable industrial packaging, opines the company. RKW highlights five key advantages that make the polymer-based alternative stand out from paper bags in terms of sustainability. The name Ecore – ‘ECO’ for circular economy and RE for recycling – points to the first key benefit: material recyclability.

The packaging solution is made from pure, 100 % recyclable polyethylene. While competing paper sack manufacturers use composite that at best can be incinerated, the firm supplies a fully-recyclable solution that has been compliant with the 2020 EU standards for more than ten years. Recycling is much easier, more efficient – and requires 90 % less energy than other packaging solutions, states the firm.

40 % less packaging material

The second key advantage lies in the remarkably low film thickness. Research studies have shown that the solution reduces packaging material by up to 40 % compared to paper bags. This minimises the consumption of natural resources – and reduces packaging weight to make the sack one of the lightest on the market. Compared to paper sacks, the plastic solution reduces energy consumption and lowers storage, transport and recycling costs, adds the firm.

Reliable product protection

Thanks to its outstanding impact and tear resistance, the plastic sack is very rarely damaged during storage and transport. According to the company, these protective properties define the third key advantage of the plastic sack over paper solutions. Developed by RKW for powdery goods like cement and mortar, the dust-proof plastic packaging is the first to feature an integrated venting system. The innovation has been used for many years to reliably protect building materials and products supplied by the food and chemical industries. With 10 % less product loss compared to paper sacks, RKW Pro Vent Ecore 5 reduces CO2 by 1.4 kg per sack of cement.

Maximum moisture barrier and UV protection

Product protection is a crucial factor when it comes to sustainable packaging for moisture-sensitive goods – like building materials or chemical powders – that are energy-intensive in manufacturing. There's no point in filling these products into sacks that do not provide adequate moisture protection. In this context, product protection means environmental protection, mentions the company.

And this is the fourth key advantage: with a moisture barrier up to 40 times greater than paper sacks, the contents are reliably protected – not only against moisture, but also against air, dust and dirt, opines the firm. Combining this with optimum UV stability, the industrial sack solution significantly extends product shelf life compared to paper. The company has set a market benchmark as the first supplier of self-venting plastic sacks.

Clean overall process

Lastly, the solution ensures a clean filling process to protect users and the environment while significantly reducing the risk of contamination, mentions the company. With these five key advantages, the firm is presenting its plastic solution at Powtech as the more sustainable and efficient packaging alternative conventional paper sacks for powdery, moisture-sensitive goods.

The company will be displaying their solutions in Hall 1, Booth 1-533 at Powtech.
