How to ensure the hygiene and safety of Party Printed Paper Napkins during production?

Strictly screen raw material suppliers and require them to have complete production qualifications, quality management systems and good market reputation. For the main raw material wood pulp of Party Printed Paper Napkins, it is preferred to cooperate with large and formal forest pulp and paper integrated enterprises. Such enterprises have strict quality control processes from wood planting, logging to pulping, which can ensure the purity and hygiene indicators of wood pulp from the source.

When the raw materials enter the factory, strict inspection and testing are carried out. For wood pulp, its whiteness, fiber length, microbial indicators and the presence of chemical residues are tested. Only when all indicators meet national standards and internal requirements of the enterprise can it be put into production. For the ink used for printing, ensure that it meets the food contact grade safety standards, is non-toxic and harmless, does not contain harmful heavy metals and volatile organic compounds, and can be verified through the test report of a third-party authoritative testing agency.

The production workshop is reasonably laid out according to the cleanliness requirements and divided into clean area, quasi-clean area and general operation area. The clean area is mainly used for processes with extremely high hygiene requirements such as cutting and packaging of paper towels; the quasi-clean area is used for printing, laminating and other operations; the general operation area is used for storage and pretreatment of raw materials. Effective isolation facilities such as air showers and transfer windows are set up between different areas to prevent cross-contamination.

The production equipment must be thoroughly cleaned and disinfected before and after each use to prevent residual raw materials, inks, etc. from breeding bacteria. Regular maintenance of equipment is carried out to ensure its normal operation and avoid hygiene problems caused by equipment failure. For example, the printing rollers, screens and other parts of the printing machine should be cleaned in time after use to remove residual ink and prevent the ink from drying and affecting the quality and hygiene of printing. At the same time, the sealing parts of the equipment are checked and replaced to prevent dust, microorganisms, etc. from entering the equipment.

During the production process, key control points are monitored in real time. For example, in the laminating process of paper towels, the laminating temperature and pressure are controlled to ensure that the laminating layers are tightly combined and seamless to prevent microbial invasion. At the same time, monitor the microbial indicators in the production process, regularly sample and test the production environment, equipment surface, semi-finished products, etc., and take immediate measures to rectify the situation once the microorganisms exceed the standard.

Take various measures to prevent foreign matter from mixing into paper towels. During the storage and transportation of raw materials, use sealed packaging to prevent foreign matter from entering. Install metal detectors, X-ray detectors and other equipment on the production line to test the finished products, and promptly detect and remove products containing foreign matter such as metal, glass, and plastic. In addition, train the personnel at the production site and require them to strictly abide by the operating procedures and not bring personal items into the production area.
