These block bottom kraft bags have rectangular bases which means they are easy to fill and stand well. Ideal for confectionery, these bags look great when filled and the transparent window allows your customers to see what they are buying. The best thing about them however, is that they are completely Home Compostable due to the inside of the bag being lined with compostable Natureflex™ film

This Eco-friendly, biodegradable and compostable bag is made from 70gsm kraft paper outer and the inside of the bag is very clear 23mu Natureflex™ film, which is made from wood pulp. This means that the bags are heat sealable. They can also be folded over and taped, or used with Tin Ties

The film manufacturer recommends that the bags are stored in suitable conditions. Recommended storage conditions are away from local heat sources, out of direct sunlight, and ideally between 17 and 23 degrees Celsius.

The film manufacturer also specifically recommends that the films should not be used in applications that would involve processing, treatment or storage at temperatures below −30°C (for example, blast freezing).

Measurements can vary by several mm due to manufacturing tolerances - if size is critical please request a sample.

If you are switching from Polypropylene its important that you have a sample bag to try first as Natureflex is a different type of film and you need to be sure it will be suitable for your application. For example it may not produce such a robust heatseal as Polypropylene - Just send us an email with your address to request a sample.
