Carton is one of the commonly used packaging containers for goods. It has the characteristics of economy, convenience, environmental protection, and better protection of goods. It is very popular among users. In view of the use characteristics of the carton products, they must have good performance and stable quality. In addition to the quality of the carton products, the quality of the raw materials is an important factor affecting the quality of the carton, in addition to the performance of the production equipment, production processes and operating technology factors. The quality of raw materials is the source of the quality of the carton. For carton enterprises, only by carefully concentrating on the quality of the procurement of good raw materials can the quality of the carton products be ensured and the goods be effectively protected. The author of the carton manufacturer how to put the quality of good raw materials procurement, talk about their own shallow views for readers reference.

Pay attention to the business training and learning of procurement personnel

The purchase of raw materials for production is an important link that relates to the quality and production costs of cartons. It can be said that the quality of the company's quality and economic efficiency depends to a large extent on the professional quality of the procurement staff and the management level of the company. Carton manufacturers must be equipped with procurement personnel who have certain production process knowledge and procurement skills. They must also pay attention to professional training for procurement personnel. They must learn more about new processes and materials for procurement personnel to create good learning conditions. Enterprises can The procurement department subscribes to a number of industry newspapers and magazines, and allows procurement personnel to participate in a number of industry-related product exhibitions, so that they continue to grasp and understand the new theory and new materials of the carton production process, so as to timely understand the application of various raw materials in production Keep abreast of the carton market information; timely understand the factors that affect the quality of the carton products; timely master some knowledge related to the procurement, improve the business level, avoid the blindness in the raw material procurement, and make the quality and adaptability of the purchased raw materials. Enterprise production and quality requirements, improve product market competitiveness.

Buyers should understand the basics of raw materials related to carton production

There are many kinds of raw materials for the production of cartons, original; paper, ink, varnish, polishing oil, thinners, adhesives, starch, etc., there are dozens of large and small. Is the same kind of raw material, its performance, adaptability, etc. are not the same. For adhesives, the viscosity varies, and there are certain differences depending on the application. For example, white latex (polyvinyl acetate latex) can be used in paper containers with sticky paste, and problems of degumming and bulk quality are likely to occur during use; the viscosity of chemical paste adhesives is higher than that of polyvinyl acetate latexes. However, its price is much higher than that of polyvinyl acetate latex. According to our production experience, we need to use a certain amount of chemical paste in combination with ordinary white latex to ensure the fastness of the product and effectively avoid the occurrence of quality problems. Students produce this book. Business buyers often have to go deep into the production workshop to understand the appropriateness and quality of various raw materials used in production. At the same time, they must understand the content of the technical standards of raw materials and the relationship with their product quality, and lay a solid foundation for the procurement work. . Taking cardboard as an example, the technical standards include: quantification, tightness, folding resistance, transverse index, breaking index, water absorption, and moisture content, among which the values ​​of the lateral pressure index and the burst index index. It has a greater effect on the strength of the carton; while the paper with high basis weight and tightness has a relatively better ring pressure index and burst resistance index; the carton board has a high degree of folding resistance, and the manufactured carton flap is also used when used. It is not easy to break; the boxboard with low water absorption is not easy to absorb moisture and deformed. After processing the carton, the moisture content of the carton is relatively stable, and the overall strength of the carton is relatively high. The same type of material, due to different manufacturers, the characteristics of the material and the use of effects are not necessarily the same. With a certain production strength, scale of ink production companies, due to management, equipment, combined detection measures in place, product quality performance and stability is relatively good, so when purchasing raw materials, buyers should also take the initiative to understand the performance of raw materials, Technical indicators and precautions for use, etc., can even ask the manufacturer for product specifications, in order to help better understand and master the application of raw materials, so as to better guide the production and avoid the occurrence of quality problems caused by improper use.

Put the quality of raw materials into stock

The quality of procurement of good raw materials is the basis for quality and quantity production of the company, and it is also the working principle that should be taken into consideration when purchasing. In order to ensure the quality of supply of raw materials, the following work should be done during the procurement of enterprises:

â–  Do a good job of market inspection and choose the right supplier.

Raw materials are both the source of the carton product quality and the basis for the quality of the carton product. Before purchasing, companies should conduct necessary market inspections to investigate and evaluate suppliers' production and quality, and choose one or two more suppliers for the same raw materials to facilitate comparisons and finally select quality. The suppliers who pass through are the main targets of the supply of raw materials for the company, so that they can get the maximum benefit in both price and quality.

â–  Quality of good order contracts to ensure the quality of raw materials.

Ordering contract is an important means in the production and business activities of enterprises. After confirming the supplier, besides signing the contract, besides loading the delivery item, price, quantity, time, etc. into the contents of the contract, it is very important that the quality requirements, acceptance methods, and quality problems during use of the raw materials should also be applied. The processing measures written into the contract can play a powerful role in restraining the effectiveness of ensuring the stability of the supply of raw materials and meeting the requirements of enterprises to improve product quality.

â–  Review suppliers and ensure the stability of raw material supply quality.

Reviewing suppliers is one of the manifestations of advanced management. The assessment of suppliers is mainly based on the use of their raw materials in the production of the company, such as the economics of the use of materials, the adaptability and the stability of quality. Suppliers who frequently fluctuate in the quality of raw materials and affect the normal production and quality of the enterprise must consider using them to eliminate the use of raw materials to ensure the quality of raw materials.

â–  Accept acceptance according to the quality standards of raw materials and eliminate any non-conforming product.

Enterprises must establish a raw material inspection and acceptance system, according to the actual situation of the company, to carry out sampling inspections and full inspections of the raw materials in the warehouse. Enterprises must be willing to invest in the purchase of some necessary testing equipment so that the quality of raw materials can be scientifically and accurately detected, and non-conforming products can not be put into storage, so that the source quality of production can be effectively controlled. The manufacturer of the author's factory established a laboratory to purchase ZSD-3 electronic compressive strength tester, YQ-ZB-8 paper and paperboard folding resistance tester, and ZUS-20 corrugated board thickness in order to strengthen the control of the quality source. Meters, YB electronic balances, SC69-02C Moisture Analyzers, etc., which test the incoming paper, effectively control the quality of incoming paper, and receive good results. The value of. Pay attention to quality tracking and control during the procurement process

The task of the buyer is to run the market to purchase, but after the raw materials are purchased, it does not mean that the buyer's task is completed. We must clearly understand this. Only when the purchased raw materials get the economical and applicable results in production, but also can better guarantee the quality of the products, the procurement task is considered to be successfully completed. Purchasing personnel should pay attention to strengthening their business literacy and continuously improve their purchasing skills. They must always go deep into the first line of workshop production, systematically track and understand the appropriateness and quality of raw materials, and promptly notify suppliers of raw material problems. Consultation, feedback, and even complaints, economic losses caused by the quality of raw materials to produce economic losses, the only way to make the source of product quality get a powerful and effective control. To scientifically and reasonably control the procurement of raw materials

Scientific and reasonable purchase of raw materials is an important link to ensure the quality of carton products. The raw materials for the production of cartons: inks, adhesives, starches, etc. all have a certain shelf life, and the raw materials that have passed the shelf-life, if used for production, will affect the quality of the cartons. When purchasing, it is necessary to strictly control the procurement of raw materials in accordance with the actual situation of the company, and to establish the accounting of raw materials, do a good job in the identification of raw materials, so that advanced materials can be used first. Is the corrugated paper, cardboard, white paper and other base paper, can not store too long, so as not to put too long on the paper put brittle, and affect the strength of the carton.

In summary, raw materials are the source of the quality of carton products. Therefore, the quality of the carton products can be well ensured and the requirements of the market can be satisfied only if quality procurement of good raw materials is used scientifically, reasonably and correctly.
