This is the earliest form of wrapping film, and more packaging forms have been developed from this 2. Full width packaging This kind of packaging requires that the film width is enough to cover the tray, and the shape of the tray is regular, so it is suitable for use with a film thickness of 17-35μm 3. Manual packaging This kind of packaging is the simplest kind of wrapping film packaging, the film is loaded on a rack or by hand, and the film is rotated by the tray or the film is rotated around the tray. Mainly used for repackaging after the packaged pallet is damaged, and ordinary pallet packaging. This kind of packaging speed is slow, and the suitable film thickness is 15-20 μm; 4. Stretch film wrapping machine packaging This is one of the most common and widespread forms of mechanical packaging. The tray rotates or the film rotates around the tray. The film is fixed on the support and can move up and down. This packing capacity is very large, about 15 to 18 trays per hour. The suitable film thickness is about 15-25μm; 5.

After the binding force is moderate, tighten the hexagon socket set screw. 2. Adjustment of belt width and joint opening. When the belt width is uneven or the belt of another width is replaced, the left and right belt insertion slots must be adjusted. If the slot is too narrow, the belt insertion will be difficult; if it is too wide, the belt will be joined after baling There will be misalignment. Generally, the width of the slot should be about 0.5-1 mm wider than the width of the belt. 3. Adjust the temperature of the ironing head of the baler

When using the baler, you need to pay attention to those problems
Steel rolling mills, recycling and processing industries, non-ferrous and ferrous metal smelting industries, and renewable utilization industries Y81 series hydraulic metal balers can pack various metal scraps. Extrusion of qualified charge of various shapes such as cuboid, octagon, cylinder, etc. can not only reduce the cost of transportation and smelting, but also increase the speed of charging. There are shadows of balers in these areas. So what should I pay attention to when using the machine? 1. Please confirm the power supply used by the machine, and do not insert the wrong power supply. This machine adopts a three-phase four-wire system. The flower wire is the grounding neutral wire for leakage protection. 2. Do not touch the heating plate directly with your hands. 3. Do not stick oil on the surface of the belt roller.

How to choose a good quality packing tape
The packaging belt industry has experienced many years of development. The quality of packaging belts in the market is uneven, and the price ranges from tens of yuan to several hundred yuan. In the procurement process, companies often only pay attention to the price per ton, while ignoring the actual length of each ton of packing tape. This deformity concept has also affected some packing belt manufacturers. There are some cheap and heavy belts such as sandwich packing belts, ton bag packing belts, recycled material packing belts, etc. in the market. The baler, but the sandwich packing belt, the ton bag packing belt, and the recycled material packing belt have very low breaking strength and poor bonding strength, which will affect the packaging quality of the product. So, how do we differentiate when purchasing packing tape?

Why are the prices of PP packing belts different?
In fact, there are three obvious reasons: the first point is that the quality of the packing belt is not good. The second point is that the merchant may estimate that the weight will be reduced, the weight of the box will be increased, and so on. The third point is that you may not find it, that is, the production process is unscientific, so the relative production cost is also small, and the price will be relatively cheaper. When buying PP packing belts, you can't just consider the price. As the saying goes, "you get what you pay for". Let me help you understand the things you should pay attention to when buying PP packing belts: 1. Scale weight : Whether the weight per meter matches the indicator declared by the manufacturer.
