Recently, the China National Standardization Administration (SAC) issued the national standard "Limited value of energy efficiency and energy efficiency rating of positive displacement air compressors".
This standard specifies the energy efficiency limit value of the volumetric air compressor, target energy efficiency limit value, energy conservation evaluation value, test method and inspection rules.
This standard applies to direct-coupled portable reciprocating piston air compressors, miniature reciprocating piston air compressors, all-oil-free reciprocating piston air compressors, commonly used fixed reciprocating piston air compressors, general oil-injected screw air compressors, general Single-screw air compressor with oil injection and general air-slide vane air compressor.
For the T-Shirt Bag Making Machine, we have automatic machine with auto puncher to make the handle; also we have the sealing and cutting machine, then with hydraulic pressure puncher to make the handle.

The hot sealing and cutting knife makes the bottom welding of the bag much more stronger than cold bottom sealing machines. The raw material cost keeps increasing, we design the machine suitable also for recycled material or CaCO3 blended material, which is difficult to be heated/sealed. The bottom of the bags can be well welded by our machine. Different shape of punching mould is available upon customer's request.
