Leather products produce peculiar smell, if the experienced people could soon find the reasons of the peculiar smell, the premise is he must be on the ground, look at the environment, see the packing, smell, it is difficult to judge for a single about exactly what is the cause, also cannot find out root cause, solve the substance. I have had a lot of this kind of case handling, reason is also different. This kind of circumstance also is in storage, happened in shipping, especially by sea. According to my experience of these a few years, this kind of phenomenon is usually the following several causes of:
First, the mildew flavour, bag in the storage process became moldy damp, send out a smell that tide, stale. Generally you all can feel out and figure it out. If is stale, you have to clean off mold, then do a mouldproof, ventilated place blow blow, the last in the bag a two packs of deodorization desiccant or spray some deodorant.
Second, PU flavour, PU taste not dealing with good, this is in PU material to taste agent or cover inside and agent.
Third, light focal flavour, produce the taste of things are silica gel desiccant, authentic silica gel desiccant generally does not appear this kind of circumstance, but now many are plastics, plastic in high temperature in a peculiar smell extremely easily. This kind of bad smell judgment, but you can ask desiccant, see if taste great, or tear apart a pack of, see it is black, yellow. This kind of situation immediately change desiccant, the proposal with biochemical desiccant or mouldproof antibacterial desiccant.
Fourth, glue, we do leather bag glue all do has a bad smell of flavor, glue is pollution or ammonia water is overweight, peculiar smell is rather heavy, if PU used inferior glue, then finished products in high temperature, it will shine out the smell.
If when stink happened, suggest you to packaging, take out the original desiccant, put deodorant desiccant, now deodorization effect good have activated carbon and Bio Dry deodorant bag, serious need to spray deodorant.
