FAQ: Frequently asked questions

We can use different codes to better identify some specification of the product and to offer a better service.

The most frequent cases are:

• identify the machine on which the product is manufactured, in order to easily identify the production lot in case of product control.

• Modification of the envelope (graphic, size, type, etc.).

• Replacement of worn or deformed printing plates.

You can request quotes contacting us by telephone, by writing to the dedicated mailbox commerciale@willchip.com or by filling in our form.

For standard products there is not a minimum order quantity, it is enough to purchase at least 250 € (VAT excluded). For the special items, the minimum depends on the product: please, contact us for more information.

Usually you can receive our standard products within 3 working days, as they are available in the warehouse. For all the other items, the delivery time depends on the product.

All the manufactures use the work shifts system and, at the end of each phase, there may be a lower or higher amount of pieces produced than expected. It is universally accepted a variation (tolerance) of about 10% more or less than the requested quantity.

Mater-Bi®® is a family of plastics developed, patented and produced by Novamont, containing renewable resources of agricultural origin. They are biodegradable and compostable; furthermore, they guarantee the same strength and sealing than the traditional plastic products.

A material is compostable if:

• It is biodegradable in composting

• It can be completely disintegrated in a treatment cycle

• It has no toxic effects and it does not release heavy metals in the compost produced at the end of the process

• It has no negative effects on the composting process.

Composting is an accelerated process of biological treatment of organic waste that happens in the composting plant, where natural biodegradation processes are optimized with the achievement of high temperatures. Organic waste are accumulated in plants where microorganisms, naturally present in the waste, biodegrade in the presence of air and organic substances, producing carbon dioxide, water, compost and heat. The heat is not easily to fade away and it causes high temperatures to accelerate the degradation reaction. At the end of the process, the residual waste are turned into compost.

The aim of UNI EN 13432 is to define the technical requirements for packaging waste, which can be recovered with the organic fraction.

The features, as per the laboratory test, are the following:

• No toxic substances. The packaging material must not contain heavy metals or other elements reported in the rule.

• Biodegradability. The ability of the packaging material to be converted into carbon dioxide due to microorganisms, as it happens to the natural waste.

• Decomposition. The fragmentation and loss of visibility in the final compost (absence of visual contamination).

• Absence of negative effects in the final compost. The packaging material should not contaminate the compost at the end of the process, decreasing its quality.

Each of these points are necessary for the definition of a “compostable material” but alone, is not enough.

No, Mater-Bi® ® is manufactured using only biodegradable constituents. It does not contain traditional non-biodegradable polymers.

The Mater-Bi® material can be worked using traditional systems, with lower extrusion temperatures than the standard ones and the derived wastes can be regenerated with techniques similar to those used for plastics. Furthermore, it can be printed with water-based inks or solvents, with all the printing technologies and without other treatments. Concerning our Mater-Bi® bags, the seals are strong as the standards products ones as well as the machines speed production.
