Corrugated Paper Warehouse Management - Inventory Management

Inventory is a big aspect of occupying corporate liquidity. How to reduce inventory as much as possible, reduce inventory costs, and complete the supply of production on time are the most realistic issues in inventory management. Companies are increasingly aware that in order to gain a firm foothold in the competition and seek development, it is necessary to strengthen inventory management to reduce costs and improve the competitiveness of enterprises, especially for a competitive micro-profit industry such as corrugated boxes. It is important.

The inventory management of corrugated box companies mainly includes two parts: raw paper inventory management and finished product inventory management. The base paper accounts for about 60%-80% of the cost of corrugated cartons. The base paper stocks occupy very large amounts of liquidity. Therefore, the control of raw paper stocks is the key to reduce costs. This paper mainly discusses the following stock management of corrugated paper box companies. Peer reference.

In order to improve the efficiency and management of the paper storage operations, it is necessary to manage the location of the warehouse, define the area layout of the warehouse correctly, and reduce the movement time of the base paper. At present, corrugated box companies mainly use the following types of control methods for base paper inventory management:

Accounting Card Label Management

Billing card label management means that the product information of the base paper is manually marked in the form of a card label and is hung on the corresponding base paper roll. The product identification and the entry, exit and storage of the warehouse are all handled by hand-written accounting. This management method There are many human factors, and the phenomenon of inconsistency in the account card is very easy to occur. It is only suitable for enterprises with small business volume and immature conditions.

Bar code management

The unique name, model, specification, origin, date, width, and quantity of the original paper roll are allocated to the unique code, and the bar code label is printed for the tracking management of the base paper, and the inventory of the base paper of the warehouse is recorded according to the warehouse location of the warehouse. When the base paper is stored in the base paper The warehouse barcode number corresponds to the product barcode number. When the library is out of the warehouse, the first-in-first-out or batch management is implemented according to the inventory time of the original location paper of the warehouse, and the warehouse entry, exit, and deposit management are accurately completed.

The use of bar code technology combined with information processing technology ensures the accuracy of inventory levels, guarantees necessary inventory levels and movement of base paper in warehouses. Coordinating with warehouse delivery, ensuring the optimal inflow of raw paper, storage, and outflow of warehouses. RF card management

RF card (referred to as PF card) is an integrated circuit card that transmits data wirelessly. It has strong anti-fouling properties for water, oil, and pharmaceuticals. It can also be read in dark or dirty environments. data. The RF card is in a non-contact operation state during reading and writing, which avoids mis-operations such as reading and writing errors due to poor contact, and avoids the influence of external and harsh environments such as dust on the reading and writing of the card, and is transparent and repeatable. The unique advantages of use, data storage capacity, and security. Bar codes are read-only, need to be targeted, can only be read one at a time, and are easily damaged, so the barcode may be replaced by a PF card.

With the RF card, you can instantly get the stock status of the base paper in production management, discover it and process it instantly. Regardless of where the paper is flowing, the flow of the base paper can be automatically recorded regardless of whether the base paper is used multiple times or for single use. This management method can make a written report on the base paper and each location of each roll in the warehouse, periodically inventory the warehouse area, reduce the manual entry, ensure that the error rate is reduced to zero, and optimize the warehouse Logistics management. At present, International Paper has applied radio frequency cards to the base paper tracking in its warehouses to assist in inventory management.

It is best to use vertical pallets, ie standing yards, for storing the base paper for storage. This prevents the reel from being deformed and the code is high and stable, which can increase the storage capacity. There must be a certain amount of space between pallets and pallets for easy viewing and shipment. The base paper in the warehouse should be used according to the original arrangement of first-in-first-out.

The base paper warehouse should be kept dry and well ventilated to prevent rain and sunlight from exposing, because as the temperature rises, a large amount of moisture will make the base paper brittle, yellow and warped. It is best to add a sleeper to the base of the base paper to prevent the base paper from being contaminated by moisture.

It is not allowed to pile up chemical products or commodities containing water and high fat content in raw paper warehouses, such as salt, fertilizer, soap, sugar, and cement. The temperature in the warehouse is preferably 18 degrees to 25 degrees, and the relative humidity is 50% to 65%. Measures to effectively reduce the stock of raw paper by standardizing, reducing the type of base paper

The combination of paper quality and width in each section is a type. Too many types of base paper are the main reasons for the improper purchase of base paper, excessive stock of base paper, and frequent replacement of corrugating machines. The type of base paper in foreign carton factories is much less than that of domestic equivalent carton factories. It is only about 20% to 50% of the domestic base paper varieties.
From a local point of view, the trimming of an order has increased, but overall, the management of the paper procurement and inventory, and the number of paper change machines for the corrugating machine have been greatly improved. As a company, it is a challenge to find a balance between the trimming of orders and the control of total paper loss. Implement supply chain management to improve industry competitiveness

Corrugated cartons are a supporting industrial product of raw material processing. As a result, corrugated cartons have a relatively fixed and close relationship with upstream suppliers and downstream users, and the entire supply chain is shorter than the general consumer goods industry. Therefore, implementing supply chain management in the carton industry is both necessary and feasible. Not only can help companies reduce inventory, achieve "replacement of information with information," but also help companies reduce procurement costs, ensure delivery time, and enhance corporate competitiveness.

Promote the development of zero inventory management

Zero inventory management refers to the general term for the technology that minimizes the entire process inventory by organizing supplies in accordance with JIT (Just in Time) production in the production and distribution areas.

Zero inventory is a special inventory concept. It does not mean that the storage quantity of some or some items stored in warehouses is truly zero, but that inventory is minimized by implementing specific inventory control strategies. The zero inventory strategy can effectively reduce production costs, reduce inventory costs, accelerate liquidity turnover, improve product quality, and shorten product production cycles.

In the current market competition environment, the customers of corrugated box enterprises have already pushed forward the production methods of Chuanxia. Customers have generally adopted the form of production delivery subject to immediate notification. To meet the needs of customers with multiple varieties, small batches, and varying demands, the number of customers is reduced. Inventories of corrugated cartons for JIT production are imperative. Effective implementation of the JIT production method is the first step toward the goal of zero inventory. Corrugated cartons must have confidence in the implementation of zero inventory management.
