With the daily increase in the export volume of industrial products in China, the demand for industrial product packaging continues to increase. Industrial product packaging has become an important part of the product quality assurance system. This article mainly introduces the five basic elements of rust prevention, waterproofing, moisture proofing, mildew proofing and buffering in the protective packaging of mechanical industrial products, and the latest formulation of protective packaging standards in the national packaging standards to promote the scientific packaging of industrial products. standardization.
Most of China's industrial product packaging belongs to transport packaging. China's transportation packaging is classified as follows:
┌Single-piece packaging and transport packaging │ ┌Container transport packaging └Package packaging ├Pallet transport packaging └Integrated bag transport packaging
China's industrial products (this article mainly refers to large and medium-sized mechanical workers to come to the product) use more single packaging, 200 ~ 500kg products are mostly used sliding wooden boxes, 500 ~ 2000kg products are mostly used frame wooden boxes. This type of packaging focuses on waterproof, moisture, rust, mildew, and buffers. With the increase in export volume, container transport packaging and pallet packaging are both economical and practical, and are a better alternative to wooden box packaging. In order to promote pallet packaging, China has formulated GB/T16470-1996 "Pallet Packaging" and GB/T4857.22-1998 "Packaging and Transportation Package Unit Cargo Stability Test Method". In order to perfect the protection requirements for pallet packaging, the Institute of Machinery Science is now responsible for organizing the formulation of the national standard for “Pallet Wrapping and Wrapping Machineâ€. After the completion of the standard, the country will provide the full set of standards for pallet packaging for the majority of companies, thus ensuring the promotion of such packaging.
There are conceptual differences between protective packaging technology and packaging technology methods. In general, the tray packaging, unit packaging, sales packaging, gift packaging, and dangerous goods packaging we all call a packaging technology method. In this packaging technology method contains a variety of protective packaging technologies, such as blister packaging, body packaging, shrink packaging, stretch packaging, vacuum packaging, inflatable packaging, rust-proof packaging, moisture-proof packaging, waterproof packaging, buffer packaging and children Safe packaging, and there are a lot of protective packaging technology applied together.
The commonly used protective packaging technology in the transport packaging of industrial products is generally waterproof, moisture-proof, rust-proof, mold-proof and buffering. These five technologies can ensure the quality of transportation and packaging of mechanical industrial products.
I. Technical Standards for Protective Packaging in China's National Packaging Standards (1) Basic Standards 1. GB/T 4879-1999 Rust-proof Packaging (Replace GB/T 4879-1985) (former name)
2.GB/T 4768-1995 anti-mold packaging (replacement GB/T 4768-1984)
3.GB/T 5048-1999 moisture-proof packaging (replacing GB/T 5048-1985)
4. GB/T 7350-1999 waterproof packaging (instead of GB/T 7350-1987)
5.GB/T XXXX-XXXX Cushion packaging (shock-proof packaging, anti-vibration packaging) This standard is being developed by the Institute of Mechanical Science, and its main content includes the following main contents of the following four standards:
(GB 8166-1987 buffer packaging design method)
(JB/Z 206-84 shockproof packaging for mechanical and electrical products)
(GB/T 8171-1987 Method for testing the mechanical impact of products using buffer packaging materials)
(GB/T 15099-94 Test Method for Brittleness of Products Using Impact Testers)
6. GB/T 15719-1995 On-site foam packaging "on-site foam packaging" is also called "contour packaging", it is in the gap between the packaging container and the film covered product, into the plastic foam (polyurethane foam) The raw materials can undergo a chemical reaction (oxidation reaction in the air) to form a foamed product tightly packed product. This kind of operation is usually carried out on the site of the packaging container, and special foaming equipment must be used, so the cost is higher, and it is mostly used for large batches of precision instruments. The overall performance of this protection technology is very good.
(2) Relevant standards for protective packaging 1. GJB 145A-93 "Protective packaging specification" (replacing GJB 145-86) This standard is a comprehensive protection standard for military packaging, including: anti-static, anti-electromagnetic, radiation protection, physical and mechanical Protective (buffering), rust-proof, moisture-proof, waterproof, oil-resistant, blisters, shrinkage, peelable plastic, nitrogen and other protection technologies.
2.GJB 1182-91 "Protective packaging and packing grade"
According to the standard of transportation, loading and unloading, storage conditions and opening period of the product, the standard will be divided into A, B, and C grades. Military packaging, mechanical industrial product packaging can be used as reference.
3.GB/T 12339-1990 "Use of protective packaging material"
The standard stipulates the materials used for rust prevention, moisture proofing and mildew proofing, as well as their performance.
4. GB/T 14188-1993 gas phase rust-proof packaging materials selection rules.
5.GB/T 10455-1989 Silicone desiccant for packaging.
6.GJB 2714-1996 General specification for active desiccant in static and absorbent bags for packaging.
7. GJB 2494-1995 humidity indicator card specification.
The military standards are recommended to everyone in order to maximize the convenience of packaging workers in their work applications in the absence of national standards.
(c) Signs for protective packaging tests.
1.GB/T 4857.9-1992 Spray Testing Method for Packaging and Transportation Packages
2.GB/T 4857.12-1992 "Packaging and transportation equipment submergence test method"
3. GB/T 4857.21-1995 <Test method for anti-mildew of packaging and transport parts (replacement: GB 4769-1984 anti-mildew test method)
We believe that according to the requirements of protection technology, we should increase the establishment of national standards: GB/T 4857.××-×××דCircular Exposure Experiments for Packing and Transport Parts†to test the comprehensive performance of rust-proof and moisture-proof transport packages.
Second, the relationship between protective packaging,
Transport packaging should have a close relationship between waterproof, moisture, rust, mildew, and buffering. The following diagrams reflect the application areas and relationships of the five protection technologies.

As can be seen from the figure: waterproof packaging is an outer packaging, and moisture-proof packaging, rust-proof packaging and anti-mildew packaging are generally used in the packaging, and moisture-proof packaging is also a space protection, also known as space rust, it is Anti-rust and mildew have a fundamental role. Buffer packaging can be interpreted as mitigation of impact, and there are also some protective packaging that interacts with the basic five functions and can be used with reference to the following table.

Third, the basic requirements (a) waterproof packaging waterproof packaging is to prevent liquid water, that is, rain (including snow, frost, dew, etc.) into the package and affect the contents of the protective measures taken, belonging to the packaging and contents of the package or Other packaging measures and methods are not directly related to the volume and weight of the container. However, it should also be considered in combination with moisture-proof packaging and so on. They cannot be replaced with each other. GB/T 7350-1999 "Waterproof packaging" replaces GB7359-87 "Technical conditions of waterproof packaging." Implementation of GB/T 7350-1999 "waterproof packaging" to seize the two key points: 1 determine the level of waterproof packaging. The standard waterproof packaging grade is mainly based on the two standards mentioned in this article GB/T4857.9-1992 "Packaging transport package spray test method" and GB/T 4857.12-1992 "Packaging transport package soaking test method" to imitate Rain and flood disasters are determined by using the test time as the intensity value. This has its unscientific nature.
