With the development of technology, the emergence of packaging materials such as plastic tank lower cost in recent years, a challenge to a glass jar packaging, weight loss and reduce the cost of these two aspects is the glass jar in the future in need of attention.
Glass can looks are often bulky, but in exquisite packaging lightweight today, we can see in the supermarket shelves, glass cans packaging still occupy a large market share, the glass cans packaging with own advantages are inseparable. First, the glass cans and tin cover sealing packaging, excellent sealing performance, and the plastic bottle and other sealing performance comparison, Maguchi Tetsu plays a great advantage in the very focus on the field of food safety packaging. Second, the bottle glass cans are often large, easy filling transportation, at the same time, it is also very convenient to remove the packaging, therefore is more convenient, suitable for fruit, bean curd these lumps of packaging.
Lightweight glass bottle
Earlier, the glass bottle is the only choice, in recent years the situation has changed greatly, the glass bottle rule all the land pattern was broken, plastic bags, PET bottles and concave barrel in succession into the liquid condiment market. PET bottles in the capacity of the scale with the glass bottle is similar, but compared with the glass bottle is more portable and has better gloss, and the bottle cap can be used repeatedly; PE barrels generally larger capacity, suitable for consumption relatively quick occasions, repeatedly sealing property is also very good; and the plastic bag provides better economy.
Lightweight glass bottle in the hand to save a lot of raw materials, for a glass bottle, means to reduce the cost of. On the other hand, with the decrease in the weight of glass bottles, in the process of transportation and logistics cost will greatly save.
However, the glass bottle lightweighting is not look so beautiful. Lightweight technology of glass bottle is difficult to conquer. The bottle must be under some pressure, bottle wall thinning, glass bottles bearing pressure ability will decline rapidly. So the lightweight technology is difficult to overcome. People's consumption habits, glass bottle thick texture can reflect a product grade and luxury.
The two-way choice of glass bottle
To save energy, improve melt quality, prolong the life of a kiln. A way of energy saving is to increase the amount of broken glass, broken glass foreign the added amount of 60% - 70%. The ideal is to use 100% of the broken glass, to achieve "ecological" glass production target.
The key to improve the glass bottle manufacturing labor productivity is how to improve the forming speed of glass bottle. Molding machine is now generally take the developed countries way is to use multi group, drip feed. For example, 12 sets of double gob determinant bottle making machine foreign production of machine speed can be more than 240 / minute, more than 6 groups of single drops of material forming machine which is now widely used in China more than 4 times.
The whole production process timely controlled by computer, can guarantee to achieve the best molding conditions, ensure the high quality products, more stable and reliable operation, the rejection rate is very low. Large kiln, and high-speed molding machine, ability must have a large number of stable supply of high quality glass liquid, drop the temperature and viscosity of the best molding conditions to meet the requirements of. Therefore, the composition of raw material must be very stable, the developed countries of the glass bottle production enterprises with the standard raw material refining are provided by the raw material production enterprises special. Ensure furnace thermal parameters of melting quality to use digital control system, realize the whole process of optimal control.
Glass products market
Glass bottle packaging in recent years in some high-end mineral water, beverage, food and other fields have been many manufacturers reuse. This makes the glass bottle packaging orders have significant growth. However, in this regard, we believe that the glass bottle manufacturer should see through the appearance to the essence, recognize the situation, to do a job with skill and ease in the future. Glass bottle packaging in the people a new round of retro emotion and for packaging safety voice, the market demand in the unceasing enhancement. The order of the rising volume of makes us a lot of glass bottle factories close to saturation. In recent years, along with the national restrictions on high energy consuming enterprises, glass manufacturers access threshold in the continuous increase, the quantity of glass manufacturers remain unchanged, but the market demand is constantly warmer.
Now, with the development of high-end food market, does give many glass manufacturers have brought real in order. Therefore, many glass manufacturers are struggling to cope with the market, not to endanger the existence of the market under consideration of water. After all, the current market for glass bottle preferences, not glass bottle packaging improved some of the shortcomings of its own, is not a new glass bottle packaging innovation. But the market for high-end packaging packaging needs of differentiation.
So for the glass manufacturers now speaking, the status quo while the market situation is very good, but must have foresight, otherwise the good market situation will be rapid replacement. |
