Key Factors for Enhancing Production Efficiency
The production efficiency of bubble film machines is a matter of great concern. So, how can we boost their productivity? Selecting the right type of bubble film machine for different packaging products is crucial, as the actual packaging effects differ.
4 Layers Bubble Film Machine
For valuables and fragile items, using devices capable of producing double-layer composite bubble membranes is essential. This ensures the effective and rapid protection of valuable items. In contrast, for general products that are less likely to be damaged, choosing bubble film equipment with fewer layers can enhance cost-effectiveness and packaging efficiency.
The selection of an appropriate bubble film machine relies on key performance parameters. There are various models and specifications available to meet different product thicknesses and production capacities. Thus, picking equipment that matches specific manufacturing requirements is vital for improving productivity.
Currently, bubble film production equipment available in the market usually has a tube diameter of approximately 210cm. A smaller diameter makes the cylinder less prone to breakage but restricts manufacturing efficiency and production capacity. On the other hand, a larger cylinder diameter may lead to cracking at the support points.
The bubble film machine is designed for the continuous production of polyethylene compound foam through a single molding process. It features stable performance, durability, strong adaptability, ease of operation, and high efficiency. The resulting bubble molds, also known as air cushion molds or bubble paper, are moisture-resistant, shock-resistant, and suitable for packaging and cushioning purposes.
Bubble Film Formation Process
Bubble molds are produced using low-density polyethylene via the bubble film machine. But how are the bubbles on the bubble mold formed? Firstly, resin materials are selected based on the bubble mold's hardness requirements, granular materials are mixed, and the mixture is transported for further processing.
The granular material is heated and melted at a high temperature of 230°C in an extrusion molding machine and then transferred to a blowing machine. The melted resin is formed into a thin mold through extrusion and expansion. By injecting air at the mold exit, a cylindrical film is produced, and the air injection ensures its uniformity. The cylindrical thin mold is then cut into two pieces and wound onto rollers.
Through pressure rollers, the two layers of thin molds are transformed into a double-layered thin mold. The softened thin mold is wrapped around vacuum rollers with round holes, enabling the creation of actual air bubbles. The vacuum roller extracts air through numerous small holes, forming air bubbles on the thin molds. These bubble molds can then be cut and packaged for use.
Maintenance and Operation Tips
It is essential to regularly check the temperature control and heating devices of the bubble film machine. Adjust the heating temperatures within the indicated range as necessary. Monitor the traction speed and control the mold thickness. Ensure that the thickness is uniform and that the folding diameter meets the specification requirements.
Selecting the right bubble film machine depends on key performance parameters. Different models and specifications are available to accommodate various product thicknesses and production capacities. Therefore, choosing equipment that aligns with specific manufacturing requirements is vital for enhancing productivity.
