In the rubber situation The problem has accumulated. All sectors are mobilized. The idea is to solve the problem of falling rubber prices. Or the output overflow. Overpriced The rubber growers. Have been affected by the same. This is a problem that many sectors. Trying to find a way out Research or development Products that can be used to produce rubber. It is another way to alleviate the suffering of farmers. The characteristics of rubber processing. There are many types of rubber raw rubber rubber and rubber. And have specific properties in themselves. The obvious is flexibility. Rubber quality in each production source is not equal. It is a problem of creating products with many components of rubber. But many of the products do not require the quality of the rubber. The problem is less. Such as shockproof materials in various packaging. Especially the material inside the packaging. For glass and ceramic products Only flexible features are needed. The rubber coating on the material has been invented many experiments. Be it on wood on fabric etc. as well as paper. But rubber coating on paper. To use for such purposes. It is made to be shockproof material by means of the pump in the packaging. There is no such trial. Researchers have the idea to study and develop the process. Cushioning material from rubber coated paper. To be suitable for packaging applications for glass and ceramic products. With regard to the ability to actually use. Value for money. Industrial production The satisfaction of the consumer. And the standard of packaging. The researcher found that. Applying the varnish on three variables and mixing the three compounds results that if the coating is applied on a material with a resilient property it will increase the elastic properties of the material. Corrugated paper is particularly suitable because the rubber can be inserted into the corrugated paper inside the corrugated paper. The test results are very good. Satisfaction I found that the content provider is very satisfied with the format and usage. But in weight it is also a problem because of the water that makes the weight of the packaging. The researcher should consider that the weight of rubber latex should be improved.
