การศึกษาและพัฒนาวัสดุกันกระแทกจากกระดาษเคลือบน้ำยางพาราด้วยวิธีการปั้มตัดขึ้นรูป ในงานบรรจุภัณฑ์ สำหรับผลิตภัณฑ์แก้วและเซรามิค
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.

The objective of the research is to study and develop a shock and impact absorber material. This material are make from papaya stem and to be used in glass and ceramic packaging. This research is also focus on recycling agriculture waste 1.to added value 2.minimized waste and trash and 3.support the idea of saving the environment and improve economic in community. The process of making this shock and impact absorbing material started with setting the papaya stem in to a frame shape and use natural bonding such as rubber to keep it in that shape. After that it become a shock and impact absorber sheet. The researcher chose six items as case study and they are; tall glass short glass glass doll small cup vase and ceramic doll. All these six items had to go through a standard packaging test and a satisfaction questionnaire. Papaya stem after it has been treaded and soaked in water it become a net like material and bond well with the natural bonding material. In this case it was rubber. After it dry it is soft enough to be used as glass and ceramic items yet strong enough to pass all the packaging test. These shock and impact absorber material performed well with the test and the satisfaction questionnaire and receive high score on the test in both the design and the function.
