Technical requirements for paper for paper-plastic packaging materials
Paper-plastic packaging materials are widely used in various industries due to their durability, flexibility, and eco-friendly nature. To ensure the quality and safety of these materials, there are specific technical requirements that paper used in paper-plastic packaging must meet.
Firstly, the paper must have a certain level of strength and tear resistance to withstand the rigors of the packaging process and transportation. It should also have good printability to ensure clear and vivid printing of logos, product information, and barcodes. Additionally, the paper should have a smooth surface to provide a good base for lamination with plastic films and coatings.
Furthermore, the paper used in paper-plastic packaging materials must meet food-grade standards to ensure the safety of the packaged products. It should be free from harmful chemicals, odors, and contaminants that could potentially contaminate the food or affect its quality. The paper should also have good barrier properties to protect the contents from moisture, oxygen, and light, thereby extending the shelf life of the products.
In conclusion, meeting these technical requirements for paper used in paper-plastic packaging materials is essential to ensure the quality, safety, and effectiveness of the packaging. By adhering to these standards, manufacturers can produce high-quality packaging materials that meet the needs and expectations of consumers and businesses alike.
