The pure material packing belt has long characteristic unit length and low use cost, and is particularly suitable for use on a fully automatic baler. The packaging efficiency is high, the labor is saved manually, and the cost is saved.
Captive Screws are fasteners designed to remain attached to guards or equipment. A conventional screw typically passes through a clearance hole in one part and then screws into a threaded hole in a second part - so the first part is clamped to the second. However, when the fastener is unscrewed from the threaded hole in the second component, it can easily separate from the first one.
A captive screw is designed to prevent this from occurring. It can freely rotate within the first component, with some axial movement, but it`s unable to separate from it. Captive screws are used when fasteners must remain attached to equipment, such as in cover panels. They are a requirement for several machinery safety standards.
Captive screws have a normal thread and a reduced diameter for the rest of the screw length. A captive screw is usually used with a retaining washer or a retaining flange. These have a hole with a short-threaded length. The threaded portion of the captive screw is screwed through this hole until the reduced diameter can pass freely through it. The washer or flange is then captive on the screw.
To install a captive screw on a panel using a retaining washer, the screw is first passed through a hole in the panel. The washer is then screwed onto the captive screw, until the reduced diameter section is reached, retaining the screw on the panel. To install a captive screw using a retaining flange, the flange is first pressed onto the panel. The captive screw is then screwed into the flange until the reduced diameter section is reached and the screw is retained.
Other forms of captive screw are also available that have pre-fitted caps in place of a retaining washer or flange. These caps can be pressed, bonded, or screwed into the panel or equipment to which the screw is to be retained.

The pure material packing tape is made of pure polypropylene as raw material, and the processed belt has a long number of meters, high hardness, strong pulling force, small inclination, stable performance, bright appearance, and is deeply trusted and praised by users, and ordinary packing belts. In comparison, the ordinary package has a high basis weight, a short length, a small pulling force, and a dark appearance. Since the ordinary packing tape uses a small amount of polypropylene at both ends of the tape, a large amount of lime powder is added in the middle, so the pure material tape has It is impossible to use the characteristics, and the use cost is more than 2-3 times higher than that of pure materials.
The pure material packing belt can be used at the same time on the semi-automatic and full-automatic packaging machine. The performance is stable and the appearance is neat. At the same time, the grade of the product is also improved, and it is not easy to be loose in the transportation process, and the small stretchability facilitates long-term storage of the product.
