Polypropylene film paper cup packaging machines is designed for the special packaging needs of polypropylene film and paper cups. Compared with ordinary sealing machines, the advantages are as follows:
1.More adaptable to packaging materials.
Polypropylene film characteristics: PP (polypropylene) film has temperature resistance, good sealing performance, high tensile strength, suitable for high temperature sterilization or long-term preservation of the situation (such as medicine and food packaging). Ordinary sealing machines generally only supports polyethylene film or ordinary plastic film, cannot meet the technical requirements of polypropylene film.
Paper cup Compatibility: Polypropylene film paper cup packaging machines is suitable for composites such as paper andplastic composite bag, Tyvek packaging bags, while ordinary sealing machines is mainly used for single-use plastic bags bag or aluminum foil bags.
2.More Precise Sealing Effect
Sealing and Non-Destructive Peeling: PP film paper cup packaging machines must meet the dual criteria of "Seal" and "Non-destructive Peeling":
Seal: Under disinfection or storage conditions, the packaging bag is intact to prevent external contamination;
Non-destructive peeling: No paper scraps or plastic residue remains when unpacking, avoiding secondary contamination of equipment (e.g. medical equipment).
Normal sealing machine due to inaccurate temperature temperature control may appear the sealing material excessive melting, resulting in paper scraps or plastic shedding.
Stripping Force Uniformity: International standards require stripping force ≥ 1.5N / 15mm for paper-plastic bags and consistent the tensile force value for all parts of the sealing line. Polypropylene film paper cup packaging machines, using the tensile tester to test, shows the smallest data deviation, accuracy is difficult for ordinary sealing machine to reach.
3. More Precise Temperature and Pressure Control
Temperature control: polypropylene film paper cup packaging machine temperature difference control within 1% to ensure uniform sealing; ordinary sealing machines temperature control error in the range of about 5~10°C, easy to cause local overheating or weak sealing.
Pressure control: polypropylene thin-film paper cup packaging machine have stable pressure and low fluctuation range, and the pressure and temperature of ordinary sealing machines need to be adjusted frequently, which increases uncertainty and can not reliably prevent microorganisms from entering.
4. Richer Functional Expandability
Auxiliary Functions: PP thin-film paper cup packaging machine can be integrated with continuous sealing, printing, information storage and traceability, USB port, barcode scanner input, WiFi connection, etc., to meet the needs of industrial production; ordinary sealing machines has limited function and mainly supports basic sealing operation.
Customization Capability: For containers of different shapes,such as square and oval cups, polypropylene film paper cup packaging machine can be sealed using custom moulds, while ordinary sealing machines typically only support standard round or regular shapes.
V. Higher operational stability and durability
Equipment precision: polypropylene film paper cup packaging machines in appearance, workmanship precision, operating stability and other aspects are significantly better than ordinary sealing machine, after long-term use of low failure rate.
Material Adaptability: Polypropylene films are not easily deformed at high temperature, have lower water vapor permeability than PVC and PET, and are suitable for long-term storage. The use of PE films or aluminum foil bags for ordinary sealing machines may be limited due to their material properties.
