How plastic machinery can help reduce the weight of plastic containers
In recent years, the use of thin-walled plastic bags has quietly become a major market trend. In Europe and the United States and other countries, lightweight plastic packaging has long been not a strange topic. Take the example of the United Kingdom. In 2013, the number of plastic shopping bags purchased by British consumers in domestic supermarkets was 8.3 billion, a decrease of 32% compared to 12.2 billion in 2006. However, this figure increased by 3.2% compared with the 8.1 billion in 2012. Wrap market analysts explained that this was mainly due to the “lightweight†development of the shopping bags and the use of recycled materials that reduced the use of the original polymer in the production of shopping bags by 48%.
In order to reduce the waste of plastic waste shopping bags and give full play to their value, many supermarkets and retail stores in the UK will place recyclable equipment at the entrance to collect used shopping bags for recycling. It is reported that under the advocacy of merchants, nearly 40% of plastic shopping in the UK will be turned into waste every year for secondary use.
In addition to collecting waste plastic shopping bags, British reproductions are also very supportive of the British government’s next year to impose a five-pill/one-plus tax plan on plastic bags used in supermarkets and large department stores. They believe that the provision of paid shopping bags for plastics can further standardize consumers' environmental awareness and thus reduce the use of plastic shopping bags.
Lightweight plastic packaging can effectively reduce costs
In general, plastic bottles, plastic cans, plastic hoses, and plastic caps and other types of containers are more simple to complete weight loss.
More and more companies are selecting plastic machinery that can produce very good packaging, produce faster, and have a stronger and lighter weight of packaging. When the daily chemical company sells its products in large quantities, a small reduction in the amount of resin used on each package can be achieved. Bringing considerable economic benefits to the company, especially given the unprecedented advancement in the quotations of resin materials, more and more companies have announced a thickening interest in lightweight packaging.
After a plastic package has been successfully weight-reduced, fewer resins are needed in the injection molding skills. Because fewer packaging materials are used, lightweight packaging is very beneficial to environmental protection, but it is not Her only advantage, lightweight packaging also has the advantages of using more and more, for example, can effectively reduce costs.
In order to reduce the amount of resin used for plastic bottles or caps, the skills needed for injection molding are changed, and the use of strips of continuous injection molding techniques is used as an alternative to the back injection molding skills. The injection molding skills of the container caps are completed, the strips in the middle of the mold are peeled off, and the bottle is changed. The thread of the cover, so that the weight of the lid can be lowered, and the policy of lightening the weight is completed.
We know that plastic buckets range in size from 1 liter to hundreds of liters, and plastic buckets cover a very wide range. At present, some plastic buckets in the market do seem to be overweight in our opinion. This is incompatible with light weight. The awareness of lightweighting in the plastic barrel market is too weak. From plastic barrel manufacturers to plastic barrel buyers. It seems that all people rarely notice this industry trend.
In fact, the lightweight plastic bucket is more space than the plastic bottle and the glass bottle. The barrel of the plastic bucket is thicker. However, plastic drums are often used as packaging materials for chemical raw materials. It is necessary to be very cautious when carrying out lighter weights. Otherwise, it is easy to have big problems.
Promote the plastic barrel industry from the manufacturers to the buyers to form a light awareness, whether it is for the community or the manufacturers have a positive meaning, hope that the relevant departments to guide more.
Ground earth anchors can be divided into anchor piles, anchor points, anchor ingots, and drag pits. In lifting operations, ground anchors are commonly used to fix drag ropes, cable wind ropes, hoists, guide pulleys, etc., ground anchors are generally prefabricated with steel wire ropes, steel pipes, and reinforced concrete Buried pieces, logs, etc. are made by burying them in the ground.
1. The ground Earth anchors used for hoisting should be made strictly according to the design, and concealed engineering records should be kept, and overloading is not allowed when using;
2. The ground anchor pit should be dug into a right-angled trapezoid shape, and the angle between the slope and the vertical should be 150 degrees. The anchor depth is determined according to the comprehensive situation of the site;
3. The angle between the drag rope and the horizontal plane is generally less than 30 degrees. The exit point of the ground anchor foundation pit (that is, the place where the wire rope passes through the soil layer and exposes the ground) is 2.5 times the depth of the front pit and within 2 meters on both sides of the foundation pit. No trenches, cables, underground pipelines and other structures, as well as temporary trenching, etc.;
4. No water should accumulate around the ground anchor;
5. Ground anchors are not allowed to be installed in the forward direction along the embedded parts
