Recycling film packaging is an important step worldwide to reduce plastic waste and keep valuable raw materials in circulation. Everyone can contribute: carefully separate film packaging from other waste, remove food residues and dispose of it via the designated collection systems. Modern recycling plants transform clean material into new granulate, from which packaging, bags or technical films are made again. Every correctly disposed-of film means less waste in nature, less resource consumption and a cleaner future – everywhere in the world.

The Block Bottom Bags Natron Natural with Window combine natural Natron paper with a transparent OPP viewing area on the front. This way you get the sustainable paper look of the Natron bags and show the contents at the same time – ideal when look and trust at the point of sale count together.
What the window variant is suitable for
The window is worthwhile wherever the contents sell themselves: with colourful, high-value or distinctive products that customers want to see before they buy. The surrounding paper surface carries your branding and ensures the natural overall impression.
- Coffee beans and tea blends with visible quality
- Muesli, nuts, dried fruit and granola
- Colourful confectionery, pralines and baking mixes
- Manufactory and gift products on the natural food shelf
Material and properties
The bag body is made of Natron paper, the transparent window of crystal-clear OPP. The bags are food-grade to EC 1935/2004 and EU 10/2011; the declaration of conformity (PIM) is available on request. When disposing, note that the material combination paper-plus-window goes through the packaging waste (recycling bin), as the film window can hinder clean paper recovery.
With or without window – the right choice
You choose the window variant when the contents are decisive for the sale and should be seen. If a pure natural look without a view is enough for you, the Natron Natural without window is the more single-grade paper solution. If, on the other hand, you want crystal-clear visibility all around instead of just a window, you reach for the OPP film variant with sealed edge.

Frequently asked questions about the block bottom bags Natron Natural with window
What is the window good for?
The transparent window shows your contents directly on the shelf – particularly effective with visually attractive products such as coffee beans, tea blends, granola or colourful confectionery that advertise themselves.
What material is the window made of?
The window is made of crystal-clear OPP, the bag body of natural Natron paper. This way you combine a paper look with a clear view of the contents.
Is the variant food-grade?
Yes, it is certified for direct food contact to EC 1935/2004 and EU 10/2011. We send you the declaration of conformity (PIM) on request.
How do I dispose of the bags with window?
Because of the combination of paper and film window, they belong in the recycling bin. The window can disrupt pure waste paper recovery – for single-grade paper recycling choose the windowless Natron variant.
When do I take the variant without window?
When maximum single-grade purity in paper recycling matters more to you than the view, or when your product needs no display window. Then the Natron Natural without window is the more suitable choice.
Do the bags with window stand securely?
Yes, the box-shaped block bottom gives the filled bags secure standing. The window sits on the front and does not impair the stability.
Are the bags suitable for coffee?
Yes, for beans and ground coffee in an attractive presentation. For freshly roasted coffee that releases CO₂, ask us about a valve solution, as paper and window form no complete gas barrier.
Can I print the paper surface?
Yes, the Natron paper surface around the window is well suited for your logo and label branding. We arrange printing in flexo or gravure individually, with minimum quantity.
Do I get samples in advance?
Yes, before your first order we send you free samples of the standard sizes so you can check the window size, paper and look. Enquire via the contact form.
