DS Smith’s flexible packaging division Rapak has expanded its portfolio with the launch of reinforced welding system W-Seal to offer resistant, crack-free Bag-in-Box bags.

DS Smith’s flexible packaging division Rapak has expanded its portfolio with the launch of reinforced welding system W-Seal to offer resistant, crack-free Bag-in-Box bags.

The company has developed the new welding system to create a honeycomb-like pattern in the melted plastic and offer anti-crack properties to Bag-in-Box bags during transportation.

According to Rapak, W-Seal is designed to address the risk for plastic cracking on the seam, where the dispensing tap is welded into the flexible bag.

The new technology can prevent possible cracks and leaks at the welded seam due to a stronger seal.

Rapak Europe general manager Alexander Kayser said: “W-Seal will also be a big advantage for customers that use Bag-in-Box format in e-commerce, as last-mile damages are very common in this channel.

“At Rapak, we are committed to the highest quality standards of our products, that is why we will upgrade all our customers to W-Seal, starting with our plant in Germany throughout 2019.”

The bags with the new welding system are available to customers since the middle of this year.

The new welding technique is suitable for long transit distance or changing conditions and can also be used for exports.

The company manufactures bags, fitments and filling machines for Bag-in-Box products, serving beverages, liquid food and chemical markets in Eastern Europe.

In April, Rapak North America launched a new extended tab PCSS fitment to redesign its DuraBev beverage bag.
