Big Bag Packaging Equipment Localization Becomes a New Topic
With the continuous development of China's economy and the increasing production of large-scale enterprises, how to meet the demand for 25-50 kilograms of large-bag packaging equipment in various industries is a new topic in the packaging machinery industry.
It is true that the large package of objects has existed since ancient times. Past baskets, sacks, sacks, wooden boxes, plastic woven bags, cement paper bags, etc. are all large-package containers. However, modern large-scale production puts forward higher and updated requirements for packaging. There are basically the following six functional indicators:
High-speed and high-efficiency: It can meet the requirements of packaging more than 20 tons per hour and continuous production.
Fastness: The tensile and impact strength of the bag can withstand gravity, pressure in the stack, and impact during transportation.
Sealing: Due to different packaging materials, each has different sealing requirements. In particular, the sealing performance of powdered or toxic substances and articles that are afraid of being contaminated is very strict.
Anti-mildew properties: Materials that are susceptible to moisture or mildew have special requirements for the tightness of the packaging material.
Environmental protection requirements: Protecting the environment on which people depend for survival is the consensus of the world. The level of environmental protection is a symbol of the degree of civilization of a country; therefore, environmental pollution of the packaged goods is not allowed; and bags must be degradable. Recyclable materials to mitigate environmental pollution.
Easy-to-remove performance: modern large-scale industrial production inevitably requires high efficiency, and most large-bag packaging is raw materials or primary processing products, so the packaging bag must also meet the requirements of easy disassembly and easy dumping.
Since the reform and opening up, China has successively introduced a batch of complete sets of equipment, which also provided a high-speed and high-efficiency automatic packaging machine, which satisfies the above-mentioned functional requirements according to different needs, and mostly uses degradable and environmentally-friendly packaging materials. Most of these equipment come from Japan, Germany, the United States and other countries, accounting for most of China's market. For more than a decade, developed countries have developed more rational multiple packaging methods and equipment, providing valuable reference and inspiration for China's packaging machinery industry.
In recent years, domestic industries have generally raised the awareness of the importance of packaging. This is a gratifying phenomenon. However, the packaging industry lacks guidance on large bag packaging methods and equipment selection, and falls behind the market demand. Buyers often follow the map and choose similar imported equipment. However, imported equipment is expensive. Most companies that have invested or are well-funded by the state have purchased imported equipment in the past; some technological transformation projects or small and medium-sized enterprises can only be overwhelming; the other is Enterprises exporting products, foreign parties put forward packaging requirements or provide samples of packaging bags, because of lack of information, these companies are looking for everywhere to meet the requirements of foreign parties; most of them are commissioned by complete sets of equipment suppliers to support them, but complete sets of equipment supply companies Lack of professional shopping guides is also a struggle.
At present domestic and foreign large bag packaging broad classification
Heavy plastic bag automatic heat seal packaging
The so-called heavy-duty plastic bag refers to a package of 25-50 kg of material, a single-layer bag of 0.2-0.5 mm thick PE, PP plastic film bag or aluminum-plastic, paper-plastic composite bag.
This kind of packaging has good sealing performance, especially composite bags, and the sealing process is relatively simple. As the film is thicker and has a certain degree of fastness, the aluminum-plastic composite bag also has a sealed shading effect, and the new packaging equipment is equipped with an exhaust device. The vented packaging bag withstands pressure and impact during stacking and transportation. Applicable to the sealing of flat and M-folded bags, but attention should be paid to avoiding white pollution caused by the recycling of bags; in recent years, there has been a way to make packaging bags with materials as materials, which eliminates the recycling of packaging bags and serves both purposes.
