Why don't cement enterprises use plastic pasting bags
At present, the price of plastic-woven suture bags used by cement enterprises is generally between 0.7-0.9yuan/strip. Some small cement enterprises even use 0.6yuan/strip plastic-woven bags. At present, the price of plastic-woven bottom bag is between 1.20-1.30 yuan/strip.Cement companies do not actively use plastic-bonded bottom bags first because they fear that the increased cost will not make up for it in terms of sales, thus weakening local market competitiveness or diminishing profits. After all, the price of cement plays a leading role in cement sales.Secondly, there is no organized emission in the packaging production and product transport process caused by the plastic woven suture bag. The relevant departments do not strictly monitor it, and the enterprise's own environmental binding is abandoned in the face of interests.Accordingly, although environmental expert and industry personage publicize the advantage of bag of model make up paste bottom for many years, below the standard of the cement that precedes a country is changeless, do not have the compulsion of code standard restraint, cement company also has right to choose "can use cheap need not expensive".
In fact, in the current clean production process, cement enterprises do not object to the use of plastic pasting bottom bag, the reason for not using is that they worry about their own use and do not use with regional competition enterprises, the increased cost is only their own.If the production inside same area, the packaging cement that sells USES plastic to make up paste bottom bag entirely, everybody increases cost same, solved the concern of cement enterprise to cost, sale respect.The existing standards recommend that the cement enterprises choose the two ways of plastic-braided seam bag and plastic-braided bottom bag, which will lead to unfair competition in the market.
Why are plastic woven bag manufacturers less active in "changing from seam to paste"Because of the single production of cement packaging bag enterprises, the basic production of cement this type of packaging bag, completely depends on the cement enterprise choice.At present due to cement enterprises do not use the paste at the bottom of plastic braided sack, therefore the equipment can't normal production, machine has not reached 30% (with the exception of a few companies produce other bags), and most of the cement bags enterprises because of the horse paste at the bottom of plastic braided sack equipment and losing money, response to a call for companies in tears, who will dare to cross the half step?
Difficulties faced by the implementation of "abandoning seam changing paste"2017 national cement output of 2.316 billion tons, in order to cement packing (40%), 926 million tons of cement packing need to use 18.52 billion cement bags (including paper bag, paper plastic compound bag, plastic woven bag), in terms of plastic woven bag usage each year 17 billion, the current paste at the bottom of plastic braided sack equipment three bag making machine annual capacity one hundred million, need 510 bag making machine in order to meet the market demand, is expected to domestic currently subian paste at the bottom of bag making machine a total of 2019 at the end of the year close to 100 units.That is to say, there is still a lack of 410 Formosan pasting equipment, and 683 million tons of packaging cement will not be able to use the plastic-braided pasting bags at the end of 2019 if "discard seam to change pasting".At the beginning, the cement paper bag "discard seam to change paste" can be implemented smoothly, because the usage amount of cement paper bag is relatively small and there are few manufacturers. Therefore, it is easy to complete the cement paper bag "discard seam to change paste". Under such a huge gap, it is difficult to "discard seam to change paste" in one step.On the one hand, the leading unit hopes to increase the equipment r&d and purchase investment of the plastic and weaving enterprise; on the other hand, the manufacturing enterprise is waiting for the implementation, rather than waiting for the implementation.
"discard seam to change paste" several Suggestions
1. As far as we know, the water-mud plait/pasting bottom bag which is in line with advanced countries has not been widely used in China.
2. It is suggested that the China cement association establish the industry organization of cement packaging bag manufacturers as soon as possible, and speed up the standard revision work together with the national standard revision unit.When necessary, the organization standards of the association should be established first, so as to be in line with international standards and promote the establishment of green cement factory.
3. Due to the large number of cement packaging bag enterprises, some large cement enterprises also have their own packing bag processing factories. The product market is highly competitive and the market has long-term low price competition.
4. The use of water-clay pasting bottom bag is conducive to the application of intelligent technology of cement packaging system, which creates favorable conditions for the environmental protection of cement enterprises, product shipment mechanization and automation.It is suggested that cement enterprises first use plastic-braided bottom bag in 42.5 cement packaging to guide consumption through market demand.
