1. Material selection:
Choose appropriate plastic materials according to the purpose, such as food packaging requires food-grade raw materials. Considering environmental protection requirements, degradable materials can be selected.
2. Thickness control:
The thickness of the film directly affects the strength and cost of the bag, and needs to be reasonably selected according to the purpose.
3. Printing quality:
Ensure that the printed pattern is clear and the color is accurate to avoid ink contamination or shedding. Use environmentally friendly ink and meet relevant safety standards.
4. Heat seal strength:
The heat seal temperature and time need to be precisely controlled to ensure that the bag is firmly sealed to avoid air leakage or cracking.
5. Punching position and size:
The punching position should be accurate to ensure that the bag can be hung on the wicket smoothly.
The size of the hole should be moderate to avoid the bag falling off due to being too large or too small to be hung.
6. Production efficiency:
Optimize the production process, reduce the scrap rate, and improve production efficiency. Maintain the equipment regularly to ensure stable production.
7. Environmental protection and regulations:
Comply with environmental protection regulations to reduce waste and pollution during the production process. Ensure that the product complies with relevant industry standards (e.g. food packaging must comply with FDA standards).
8. Storage and transportation:
The finished product should be stored in a dry, ventilated environment to avoid moisture or high temperature. During transportation, pay attention to preventing pressure and moisture, and ensure that the bag is intact.
