中文简体Raw material selection
Follow the standards:
When selecting raw materials, disposable tableware factory should strictly follow relevant national standards and regulations, such as GB 4806.1-2016 "National Food Safety Standard General Safety Requirements for Food Contact Materials and Products". These standards stipulate the requirements for physical properties, chemical properties, microbiological indicators and other requirements of food contact materials, and are an important basis for ensuring product quality and safety.
Preferred materials:
For plastic tableware, food-grade plastics such as polyethylene (PE), polypropylene (PP), polystyrene (PS) should be preferred. These materials have been rigorously evaluated and are considered safe food contact materials with good physical properties and chemical stability.
For paper tableware, environmentally friendly, non-toxic and harmless paper materials such as virgin pulp or recycled pulp should be selected, and ensure that no harmful chemicals are used in its production process.
For bamboo and wooden tableware, raw materials with good texture, no insects or mildew should be selected, and strict anti-corrosion treatment should be carried out.
Consider environmental protection:
When selecting raw materials, their environmental performance should also be considered. Prioritize degradable, recyclable or bio-based materials to reduce environmental pollution. Biodegradable materials such as PLA (polylactic acid) have become the new favorite in the field of disposable tableware.
2. Raw material inspection
Appearance inspection:
Each batch of raw materials is inspected for appearance to ensure that they are free of defects such as breakage, deformation, stains, etc. At the same time, check whether the packaging of the raw materials is intact and whether there is any breakage or leakage.
Performance testing:
Performance tests such as density, hardness, toughness, heat resistance, etc. are performed on the raw materials to ensure that they meet production requirements. These tests help evaluate the physical properties and chemical stability of the raw materials, thereby ensuring the quality and safety of the products.
Chemical analysis:
Chemical analysis is performed on the raw materials to detect whether they contain harmful substances such as heavy metals, plasticizers, and harmful additives. These harmful substances may cause harm to human health, and their content must be strictly controlled.
Microbial testing:
Microbial testing is performed on the raw materials to ensure that they are free of microbial contamination such as bacteria and mold. Microbial contamination may cause product deterioration or cause harm to human health, and microbial indicators must be strictly controlled.
3. Raw material storage
Environmental control:
Raw materials should be stored in a dry, ventilated, light-proof environment to prevent moisture, mold or deterioration. At the same time, the temperature and humidity of the storage environment should be strictly controlled to ensure the quality and stability of the raw materials.
Classification storage:
Raw materials of different types should be stored in categories to avoid mutual contamination. For volatile, flammable and explosive raw materials, special safety measures should be taken for storage.
Regular inspection:
The stored raw materials should be inspected regularly to ensure that they are not damaged, leaked or deteriorated. For any problems found, timely measures should be taken to deal with them to prevent the problems from expanding.
4. Raw material use
On-demand collection:
Raw materials should be collected on demand according to the production plan to avoid waste and backlog. At the same time, a strict collection system should be established to ensure that the raw materials collected meet production requirements.
Accurate ratio:
In the production process, raw materials should be used strictly in accordance with the formula and process requirements to ensure the accurate ratio of the product. For raw materials that need to be mixed, they should be fully mixed and homogenized.
Quality control:
In the process of using raw materials, various parameters in the production process, such as temperature, pressure, time, etc., should be strictly controlled to ensure the quality and safety of the products. At the same time, quality monitoring and testing should be carried out on key links in the production process to promptly discover and deal with quality problems.
5. Supplier management
Select high-quality suppliers:
Disposable tableware factories should establish strict supplier selection standards and choose suppliers with legal qualifications, good reputation and reliable product quality for cooperation. At the same time, suppliers should be regularly evaluated and assessed to ensure that they always meet the requirements of the factory.
Sign a quality agreement:
Sign a quality agreement with the supplier to clarify the quality responsibilities and obligations of both parties. The agreement should include the quality standards, inspection methods, and handling of unqualified products of raw materials to ensure the quality and safety of raw materials.
Strengthen communication and collaboration:
Establish a good communication and collaboration mechanism with suppliers to jointly solve raw material quality problems and technical problems in the production process. Promote the common development of both parties by strengthening cooperation and exchanges.
