Inspection of toilet paper

Inspection of toilet paper

Generally speaking, there are 9 indicators for paper towel quality inspection: appearance, quantitative, whiteness, lateral liquid absorption height, lateral tensile index, average vertical and horizontal softness, holes, dustiness, microorganisms and other indicators.

1.Appearance

The appearance of toilet paper, including the appearance of packaging and paper towels. When choosing toilet paper, first check the outer packaging. The packaging seal of the product shall be neat and firm without damage; the package shall be printed with the name of the manufacturer, the date of production, the product grade (superior product, first-class product, qualified product), the adoption standard number, and the implemented hygiene standard number (GB20810 – 2006).

Secondly, check the appearance of the paper. It is clean. There are no obvious dead folds, incompleteness, breakage, hard blocks, grass bands, pulp and other paper diseases and impurities. There should be no serious hair loss or powder loss when using the paper. There should be no residual printing ink in the paper.

2.Quantitative

It means that the weight or number of sheets is not enough. According to the standard, for products with a net content of 50 grams to 100 grams, the negative deviation must not exceed 4.5 grams; for products with 200 grams to 300 grams, the tolerance must not exceed 9 grams.

3.Whiteness

Toilet paper is not as white as possible, it may be that an excessive amount of fluorescent bleach is added. Fluorescent agents are the main cause of dermatitis in women, and long-term use may cause cancer. How to tell whether there is an excessive amount of fluorescent bleach? First of all, it should be natural ivory white with the naked eye, or if the toilet paper is exposed to ultraviolet light (such as a banknote detector), if blue fluorescence appears, it is proved to contain a fluorescent agent. And if the brightness is too low, it will not affect the use of toilet paper, but it means that the raw materials used are poor, so try not to choose this kind of product.

4.Water absorption

You can put water droplets on it to see how fast it absorbs. The faster the speed, the better the water absorption.

5. Horizontal tensile index:

It’s the toughness of paper. Is it easy to crack when used. Pure wood pulp paper has long fiber, high tensile strength, good toughness, and is not easy to break.

6. Softness

This is an important indicator of toilet paper products. Good toilet paper should give people a soft and comfortable feeling. The main factors affecting the softness of toilet paper are the fiber raw material and creping process of toilet paper. Generally speaking, cotton pulp is better than wood pulp, wood pulp is better than wheat straw pulp, and toilet paper with excessive softness feels rough in use.

7. Holes

The perforation index is a limit requirement for the number of perforations on the wrinkled toilet paper. The perforations will affect the use of the paper. The wrinkle toilet paper with too many perforations not only has a poor appearance, but also easily breaks during use, affecting the wiping effect.

8.Dust degree

In simple terms, there is not much dust on the paper. If the raw material is wood pulp, the degree of dust is not a problem. However, if the recycled paper is used as a raw material and the process is not handled properly, it will be difficult to meet the dust standard.

9.Microbes

All in all, good toilet paper is generally natural milky white or ivory, with fine and uniform texture, clean paper surface, no holes, no obvious dead creases, dust, raw grass, etc., while low-grade toilet paper looks dark gray and has Impurities. Touch it with your hands, the toilet paper will lose powder, color, or even hair.

On the matters needing attention of customer inspection requirement

In recent years, more and more customer inspection cases, has gradually become the existence of a lot of foreign trade enterprises habit. In spite of this, there are still many foreign trade enterprises which are misunderstanding on customers’ inspection requirement. In fact, the customer inspection requirement is not our imagination of so bad or so terrible, on the contrary, customer inspection, is also a good way to show supplier’s production power, therefore, in order to the long-term development of the enterprise, when we are faced with customers inspection requirements, don’t appear too panic, also do not appear too lost, as long as we do a good job, strive to make our enterprise management summarized  it will be ok. Below are points to help you in the situation.

One, usually do a good job of improving and upgrading the production of the enterprise

Why do customers implement factory inspection? Its main purpose is, of course, to further determine the internal strength level of a foreign trade enterprise, because only by cooperating with a high-level foreign trade enterprise can the customer obtain a stable and reliable supply of products. Therefore, in order to effectively pass the customer inspection assessment, our own strength is quite important. “Strike iron also need their own hard”, no matter how the customer factory inspection, as long as our strength is strong enough, then through the customer inspection plant is also very easy. Therefore, it is very important to improve our own strength level. We should integrate such promotion and improvement work into our daily work practice, constantly learn from it, strengthen management, and strive to achieve scientific norms and guidance for enterprise production management.

Two, make certain preparation

Even if the foreign trade enterprises usually do well, in order to effectively pass the customer inspection assessment, we still have to do a certain amount of preparation, otherwise we have the strength, but because of some small details and failed to pass the customer inspection assessment, then we are not worth the loss. Under normal circumstances, the customer inspection, generally come from two aspects of hardware and software, so if the foreign trade enterprises have enough confidence to grasp through the enterprise inspection appraisal, still cannot treat STH lightly at this moment, should be within the scope of the budget allows, in advance of their hardware and software support for a reflection and introspection, completes the corresponding correction work, to fight for at the time of inspection of customers, give customers a good impression, and thus promote bilateral trade cooperation smoothly.

Three, want to achieve the promotion on the idea

Different foreign trade enterprises hold different views on the matter of customer inspection. Some foreign trade enterprises hate it deeply, fear it and refuse the customer’s request for inspection. Such foreign trade enterprises actually shut their business out. Some foreign trade enterprises for the customer inspection fear that they can not pass the customer inspection of the factory, the whole customer inspection of the factory for them like torture pain, in fact, these situations are ultimately a matter of concept. In fact, the customer inspection is a win-win good ah, customers can make friends with you such a good business partner, at the same time after the completion of the inspection will give you some production improvement advice, this for foreign trade production enterprises themselves, is also a favorable thing ah. Therefore, foreign trade enterprises should take the initiative to change their concept of customer inspection, and strive to promote the whole concept to develop in a positive direction.

Four, positive acceptance

Finally, in fact, the customer inspection is to examine the normal for foreign trade company, as a foreign trade company completely don’t panic, as long as do their share of the work, actively accept in idea, in practice, the better to participate in the customer in the practice operation of inspection, to promote the entire customer inspection smoothly and inspection qualified by itself, eventually to promote bilateral trade cooperation smoothly.

Analysis of advantages and disadvantages of trading company and manufacturer

Advantages and disadvantages of trading company:

Disadvantage

1. More and more international buyers tend to purchase directly from manufacturers to obtain price advantages.
2. Manufacturers develop increased awareness of foreign customers. Many factories have begun to develop independently while cooperating with trading companies. Coupled with the adjustment of national policies, the export right of foreign trade has been changed from the original approval system to the registration system, and factory exports have gradually become a domestic climate.
3. The trading company does not have its own factory, there is no advantage in price, and the competitiveness of other domestic suppliers is weak.

Advantage

1. The advantage of a trading company without its own factory is that all factories in China can be their own factories. Customers’ needs are often diversified and personalized. Generally, a single factory is often difficult to meet customer requirements. The advantage of a trading company is Maximize the advantages of domestic factories to achieve customer needs.
2. Analyze the advantages of trading companies by analyzing the characteristics of international buyers and the disadvantages of factories.

International buyers are divided into 4 categories:

a. A multinational company with a procurement department in China that employs domestic procurement staff. Such companies generally purchase directly from factories or from powerful distributors. They know China very well, and the products they purchase tend to be finished products.
b. There is no purchasing department in China, but the person in charge is responsible for purchasing in China. Such companies know or understand the Chinese market very well. They have more or less experience in purchasing in China. They tend to shop around, and high outrageous prices are likely to be eliminated. Such a buyer does not necessarily choose the one with the lowest price, but will use the lowest price to find the supplier he thinks is the best service, hoping that they will accept the price.
c. Small and medium-sized enterprises that have purchasing desires in China but lack experience. Such companies are often the main target of foreign trade companies in the current situation. First of all, they often do not have a person responsible for purchasing in China. They cannot invest too much energy. The needs of customers are often diversified. The products of a factory often cannot meet the requirements of customers. This requires trading companies to take on the responsibility of integrating domestic factories to meet guest needs.
d. Have not considered purchasing in China and have no purchasing experience. The potential of this development seems relatively small, but not all. Some customers have never considered purchasing in China, but when they receive a sales letter, they just have a new project at hand, so just take a look. If the first cooperation is smooth, a long-term cooperative relationship will be established.

Disadvantages of manufacturers:

Although most domestic factories currently have a direct export tendency and have their own salemen, they still have many disadvantages:

A. Insufficient experience. Many trading departments are newly established, and salemen are also novices who only speak English. They lack experience and lack foreign trade leaders with rich experience in trading.
B. Poor ability to judge risk. Of course, everyone is afraid of encountering scams and the like, but they are more afraid than trading companies. Because there is no experience, people who can take the board often can not speak English, and people who can speak English often can not take the board. This cumbersome communication process hinders the factory’s foreign trade route is smooth.
C. Less investment. Although factories want to export, they are often afraid, unwilling or not knowing how to invest. Foreign trade needs investment. And if there is no input, how can there be output?
D. The factory’s products are single and can not meet the diverse needs of some customers.

Chinese market has advantages over Vietnam

Chinese market has advantages over Vietnam

Airpods is currently the world’s highest-selling wireless headset, and it is also one of Apple’s “explosive” products, occupying nearly 60% of the market share; and according to data from the survey agency Counterpoint, including other wireless headset brands, Shipments will soar from 48 million pairs in 2018 to 129 million pairs in 2020. The “Nikkei Asian Review” pointed out that this strong growth situation has given Apple the opportunity to accelerate the diversification of production areas without reducing production.

U.S. giants may trial production in Vietnam, many U.S. companies fall into hesitation: reluctant to Chinese market.

However, due to Vietnam’s relatively good geographical location and lower cost advantages, Apple has frequently shifted its focus to Vietnam recently. Japanese media pointed out that Apple is planning to transfer 15% -30% of the company’s hardware capacity to Southeast Asian countries, and is evaluating the possible cost impact. At the same time, the impact of this production line transfer to the entire supply chain is also expected. Will appear in 2 to 3 years.

Vietnam’s production disadvantages stand out

Vietnam’s presence in the face of Apple has become stronger and stronger, but can the former really provide Apple with an irreplaceable supply chain? According to the Vietnam People’s Daily, Vietnamese companies currently only participate in processing and assembly business, especially small and medium-sized enterprises currently only 25% of them participate in the global supply chain, while in other countries, the number is 46%, which also leads to the country’s added value of processing At a lower level. In other words, Apple will transfer some hardware capacity to Southeast Asian countries such as Vietnam, which may not be able to “load”.

On the other hand, Hong Kong’s “South China Morning Post” reported earlier this month that many Chinese and foreign companies are currently moving factories to Southeast Asia, but in fact, the business environment in Southeast Asia is becoming more complicated, especially when many foreign investors are currently in Vietnam. Waiting countries encountered various difficulties in investment. The report bluntly said: The economies and markets of Southeast Asian countries are small, but the corresponding risks are not small.

For example, Vietnam ’s labor costs are constantly rising. At present, the monthly salary of local workers has risen to US $ 140-US $ 180, which is more than ten times that of a decade ago. In addition, the working efficiency of Vietnamese workers is not greater than that of Chinese workers. Gap, which causes companies to incur additional time costs. Therefore, according to foreign media reports, many American companies relocating to Southeast Asian countries have “regretted” and are planning to withdraw from the area. Some US companies have even stated that they “will not be willing to accept the Chinese market.”
