Packaging jobs, organised by item and handling
Packaging jobs should be described by the item, the handling, and the disposal route at the destination. A retail bag, a food cover, a bin liner, and a shop vest bag are different jobs, and the homepage column names reflect that variety, with food bags, vest bags, compostable poly bags, can liners, and trash bags all appearing as column names. Those names appear on the polymer index only as column names, because they were not opened into detail, and a packaging inquiry should describe the job rather than picking a column name and assuming it fits.
Handling matters as much as the item: a bag that is carried, a liner that is filled, and a cover that is sealed face different stresses, and the inquiry should describe the handling in general terms. Disposal route matters as much as handling: a destination with industrial composting, a destination with soil disposal, and a destination with ordinary waste collection treat the same item differently. Naming the item, the handling, and the disposal route in the first message usually produces a precise reply.
Agriculture jobs, organised by crop and season
Agriculture jobs should be described by the crop, the season, and the field task, and mulch film is the leading example. The MIC showroom lists a custom biodegradable mulching film as an agricultural compostable PLA mulch covering film, and that item has its own page with MIC attribution, separate from the general category discussion on this page. A buyer interested in mulch film should open that page, because it carries the attribution and the description that belong to the MIC-listed item.
Other agriculture jobs follow the same pattern: the crop, the season, the task, and the end-of-season behaviour. A general request for agricultural plastic, without a crop or a task, is hard to answer precisely, because the same category name can cover very different field jobs. The inquiry should therefore name the job in the first message, even if the exact product is still being decided, so the company can discuss the job rather than guess it.
Disposal behaviour, named plainly
The word biodegradable covers several different end-of-life behaviours, and a buyer should state which one the project or the destination requires, rather than relying on the word alone. Industrial composting, soil breakdown, and compostable marketing claims are different behaviours with different evidence, and the destination may regulate them differently. Naming the required behaviour and any document that must demonstrate it, in the first message, prevents a mismatch that only appears when the shipment arrives or the season ends.
This site does not attach a degradation claim, a timeframe, or a test name to any biodegradable item, because the source pages list the category without that detail. A buyer who needs a specific behaviour should ask for the document that demonstrates it, and should check that document against the destination requirement before placing an order. The certificates page explains how to ask for such a document by name and how to check it on arrival.
Putting the biodegradable brief together
A complete biodegradable brief has four parts: the field, the job, the disposal behaviour required, and the commercial points. Please confirm the minimum order quantity, the lead time, and the payment terms in your inquiry before you place an order. Those commercial points are not stated on this site, because the source pages publish no fixed commercial terms, and they should be asked together with the job and the disposal behaviour, so the reply can match the specific inquiry.
The polymer inquiry checklist gathers those four parts into a form that can be sent with the first message. A buyer who works through this guide and then the checklist will usually write a brief that the company can answer in one round, while a buyer who writes without that preparation will usually spend a round clarifying the job, the disposal behaviour, or the document. The guide exists to save that round, not to replace the inquiry itself.
