According to different requirements, there are non-crystalline and crystalline plastics. In molecular structure, the non-crystalline plastic has amorphous molecular alignment, but the molecular alignment of crystalline plastic is orderly, from the appearance, we can clearly identify them by transparency, non-crystalline plastics have great transparency which crystalline plastics do not. For making cutlery set, crystalline plastic has more advantages comparing non-crystalline plastic. One important reason for plastic cutlery to be crystalline, it is because crystalline plastics have certain melting points, especially for polylactic acid since the melting points of biodegradable plastics are generally not high, it helps people to control application temperature, for non-crystalline plastics, their melting point are various. At XCBIO, our factory has both inner and outer crystalline production line to satisfy our customers.
