Short Description: Before you decide to buy a DVD case, what should you consider ? Is there any good way to distinguish a good qaulity DVD Case from a bad quality DVD cases, see the article below, and we show you how to identify them.
We are a professional DVD Cases manufacturer from China since 1988. Each year we export a lot of DVD Cases to many countries. In 2003 I had written an article about how to distinguish a good quality DVD case from a bad quality DVD cases, at that time there's few professional website talked about DVD cases, and our website ranks No.1 in google search, even though the outlook of the website is not so good at that time. And later I found this article I had wrote had been copied to many websites, most of them stolen my copyright, and put my article as their own one. Even a lot of good quality pictures we shot had been used by these commercial website. Anyway, I'm still glad, because my thoughts had been recognized by so many peoples. The following is my article about How to distinguish good quality from bad quality DVD cases, I had made some new complementarity.
1.The material. About black DVD cases, there is two kinds material to make black DVD case, one use recycled material, the other use new material combined with black pigment. If the DVD case is made of recycled material, there would be some smell, the quality is bad if the smell is strong because the material has been recycled many times. And if the DVD cases is made of new material combined with black pigment, there is no bad smell. About the super Clear DVD cases, it should use virgin material (100% new material), the DVD cases can be see through, and it is crystal clear. Good quality DVD cases have a pleasant look.
2. The Film (sleeve )outside of the DVD cases. The film should be sealed tightly and smoothly onto the DVD case, you can pull them with enough strength, if it won't get out of the DVD case, the seal is good. The film should not be too thin,otherwise it is easily broken. Right now we use 0.1mm (100 micron) or 0.08mm (80 micron) sleeve for our machine Packing DVD cases. Now some factory use 0.02 to 0.03mm film to the DVD Cases, the qaulity is too bad.
3. The hinge (spine) between the covers, you can bend the two cover by continuously open and close the DVD cases. If the DVD case is made of good quality material, the hinge will not be broken easily, if the DVD case is made of bad quality material, the hinge will be broken after you bend covers over 100 times.
4. The Locking mechanism(the core in the middle of the DVD cases which hold the disc). To test the DVD locking mechanism , you can put the DVD into it, shake it strongly, if the DVD could not be shaken out of the locking mechannism, it is good quality DVD locking mechanism.
5. The booklet clips, there is two booklet clips on one side of the DVD cases ( in some DVD cases only, i.e.: in single DVD case or multiple DVD case with inserted trays ), you can push it to the border for several times, if the holder is not broken after you bush it about 100 times or more, the quality of DVD case booklet holder is good. If the DVD case is made of bad material, it will be broken after you push it several times.
6. The weight of DVD Cases . The weight will affect the thickness of DVD case. If the thickness is too thin, DVD case will be broken easily and the shape will be protruded or concaved. Usually, for made of PP material, the weight of 14mm DVD case is about 68~70g/pc; the weight of 9mm DVD case is about 63~65g/pc; the weight of 7mm DVD case is about 58~60g/pc. [haha, above weight is a history now, now the DVD Cases are made thinner and thinner, and the weight become less than less. Some bad quality DVD cases would be opened distortedly, then cannot be put flatly on the flat floor.
