As a local packaging products wholesaler or distributor, there must be a vast amount of kraft paper bags in your warehouse. Paper packaging bag is a kind of FMCG, and if you don’t sell them out ASAP, they may be in some long-term storage problems, such as getting damp, mold, and worms. A proper paper bag storage environment is necessary. Especially to the SOS paper bags for food packaging; it relates to food safety.
The paper bag storage problems are not only happening in the wholesalers and distributors’ warehouse, some self-support cloth and shoe stores, bakeries, and groceries do. The paper packagings often get damaged because of a lack of relative knowledge. Following are the probable situations that happen during storage:
Paper is good at water absorption; a high air humidity environment is easy to make it get damp. After the paper bags absorb the moisture in the air, they will become soft, influence the appearance. And the weight capacity getting weak, serious ones will turn waste products that lose value.
Besides, an over damp storage environment is also easy to breed bacterias and mold. It does influence not only the paper bags’ appearance but also a huge potential safety hazard to food packaging.
Though says that the biggest factor of the paper bags getting mold is the wet warehouse air, some dry space will also meet this problem. That’s because, during the paper bag processing, a few drops of glue will be used for gluing. To some mold, they are delicious protein. As a buyer, you can ask the manufacturer to add moderate mildew preventive in the glue to avoid this problem from happening. Of course, it must be legal and not apply to food packaging.
The bookworms often seen in the old books are also like to live in the paper bag piles. They take the wood fiber for food and bite out many tiny holes in the paper bags. If your goods are purchased from overseas manufacturers (like JiRong, China), they will ensure no worms origins in the products. Because every container must be through fumigation in the export port and destination port, twice. This is for preventing the local environment get damaged by the alien species invasion. However, it can not make sure that the paper bags in your warehouse won’t be harassed by the local worms.
Once the worm problem comes, to the handled paper shopping bags, you can consider taking fumigation in the warehouse, but it cost high. And this method is not suitable for paper food packaging bags, they can’t contact the insecticide. So, to avoid this situation, you need regular checking of your warehouse to prevent it becomes worse.
Some paper bags in a custom printed will fade after a long storage time, and the appearance gets worse. This is because the ingredients in the pigment have oxidized, and the direct sunshine will boost this process. So you’d better store the paper bags in a sunless room. Besides, you can also judge whether the products that the manufacturer ships to you are the overstocked inventory by the printed color.
To avoid the above situations from happening, you need to build a warehouse with a proper environment. Here are some pieces of advice, take considers according to your local weather.
Never direct piling the paper bags on the ground, even they are in a cardboard box. We know that the cold air flows down, and it contains more moisture. That means in the same space, the position where closer to the ground will be wetter. Piling the paper bags on the floor directly will meet the series of damp, mold, and worms problems.
If you got less stock, you could store the paper bags on the shelf. If there are too many products waiting for a sale, you can pile them on the pallets without unwrapping the shipping package boxes, stay away from the floor as far as it can.
To the paper packaging bags, the air humidity of the warehouse is not the lower the better. Once the air is over-dry, the paper bags will become fragile, the crease may break, and the printing pigment on the surface will also turn to powder and fall. The most important is, paper is inflammable, the over-dry environment has a big potential fire risk. We suggest that the suitable air humidity of the warehouse is 50%-60%, and to control the temperature at 18℃-20℃。
If possible, it will be awesome to make a ventilated environment, such as an ample enough space, or set an air interchanger for the warehouse. It will help remove the damp air away and prevent the other products’ smells from influencing each other.
If you store the paper bags in a warehouse, you do not need to worry about this problem. But suppose someday you get a whim and decide to place the stocks under the sun, to remove the damp or worms. That I suggest you pick the weak-sunshine time. Because the direct sunshine will make the paper bags fade and the crease break.
Typically, the wholesaler and distributor with rich experience will avoid the above problem by making a reasonable purchasing plan. Paper packaging bags as an FMCG is at a low price. Sometimes the shipping cost may be much higher than the product value, especially when making a custom design order overseas.
A vast bulk purchasing can get a favorable quote, that helps to save your operating costs. But it comes to the storage problem and cost at the same time. Is there a compromise solution?
First, you’d better make long-term cooperation with a paper bag manufacturer. Because to produce paper bags need a pre-pattern. Being in long-term cooperation will save the repeated cost on the pattern. Most importantly, you can agree to a flexible supply order with the manufacturer to avoid the shipping cost fluctuation risk.
Besides, JiRong also suggests that you can take a united purchasing with the other merchants if you are a respectable guy locally. It can save a lot of money by allocating the shipping cost, and so do the manufacturer on production. Finally, you will get a much more favorable quotation.
