Generally used plastic crates, nothing more than PP material. In fact, there are many kinds of raw materials can be used to do the crate, but the combination of all kinds of or PP material popularity and the use of the performance, it should be the best (but I think **** poly PP material is also better.) . Now I explain as follows:

1. PP cheap, durable, lightweight. Pure PP material can be used directly in the turnover of food use.

2. ABS is more durable than PP, but the cost is too high and heavy. (You can use recycled ABS to reduce the cost of pulling the grain)

3.*** Poly PP In fact, in my real contact with the *** Poly PP produced by the crate before, because of the high cost of I have never thought of letting the company to use this kind of raw materials to beer crates. For example, I work in a toy factory, the owner of the use of *** poly PP beer a batch of about 2W crates, used for about 10 years, the attrition rate of less than 15% per year is less than 2% of the attrition rate.

And PP and ABS produced by the loss rate of my previous record of listed companies in Hong Kong, basically no more than 2 years will have to change all over again.
