Low-density polyethylene itself does not have degradation of performance, today's "plastic limit" is the main limitation of it.
5, polypropylene (PP), made by the polymerization of propylene, transparency is also better than polyethylene, harder than polyethylene, the restaurant is mostly packaged with the box it, made of plastic box can be put into the microwave heating.lid and spoon rest

7, polycarbonate (PC), which is bisphenol A and diphenyl carbonate for the synthesis of raw materials, has excellent impact toughness and mechanical strength, and transparency is very good, so known as "transparent metal." Commonly used in the manufacture of water bottles, cups, bottles and so on. In the production of PC process, raw materials should be completely into the plastic structure of bisphenol A component should not be released in use, but in fact often can not, there will be a small part of bisphenol A can not be fully converted to plastic, Is released into the food. Bisphenol A is an endocrine disruptor, the development of the fetus and children particularly harmful, may cause abortion, congenital mental retardation and infant mental retardation. Some studies have also confirmed that bisphenol A will interfere with antagonism of thyroid hormone and inhibit testosterone secretion, affect the boy's sexual development, hinder the formation of sperm, which may affect fertility.

Life is like a play, the mortal beings belong to a corner. The play said long long, on century; that long will be short, fleeting. Life is a drop in the fragile moments in the fleeting, with the wind, the wind for the soil, although a hundred years, but also the universe meteor across the night sky, flashed, no trace no trace, although there have been flicker, But instantly disappeared without a trace. Whether this play is sad is happy, is to be defeated, no regrets is the end to the world after a casual chic, taste over the world of bitterness sweet and sour, enjoy the world of attitudes. Back to a pupil of the colorful red Bai Mei students also not unreasonable.
Contentment often music. From the ancient times, regardless of emperors, or civilians, whether rich or poor, or men, women and children, are not detached from the universe, the trajectory of the operation. Are in the same way, but also with the same results away. Not to bring the power of the throne; Although the time of birth, but once the call to the gods, or empty-handed away naked, with the dissipation of dissipation into dust. Rich and noble people also have their own troubles and depression. Living often face frown at home, to meet the Red, 踧踖 in official circles. Poor people also have their own happiness and satisfaction, as long as they have a warm home, a stable life, enjoyable. Hi also good or sad, who can not escape that little house imprisoned dust eternal ending. From this thought, people are equal to, the equality to go, alive also equal.
Sorry to find music. Life is short, so will cherish life, so have a care of life. No matter how to come to this world, regret is always unavoidable, not experienced regret life is regrettable, it is mediocre inaction alive. With regret only makes life rich and colorful, it appears that the luxury of life. Life came from regret, regret in the hard, walked from the regret. It is regrettable to miss the meeting, but once met, it is the beauty of happiness; merits, name is not regrettable, but had tried, experienced, it is brilliant; opportunity to pass by is regrettable, but because of this Times of regret, it is not the next regret, the ability to grasp the opportunity to multiply. Ancient Sima Qian received palace punishment, is regrettable, but he and his compilation of the "Historical Records" is a glorious generation, the Butterfly Lovers love is sad, it is regrettable, but no regrets will not later eternal farewell. This left Peter regret, are beautiful. Regret will bring a new beginning, a rich life, regret will bring a happy smile, in the face of all future, unfortunately, is a brilliant life embellishment, because regret, the whole world has a civilized era.
Life is a play. Since it is a play, everyone is the role of the play, for themselves, each person is the protagonist of their own, but also supporting role of others. Any role can not be separated from the supporting role of foil and play. In this sense, people are interdependent, and no one can not and can not leave the social and independent life, not "who do not ask for" ah. The success or failure of this play is a comedy or a tragedy, is not how the supporting role, because the life of the play's planning, director is yourself, others is nothing more than your cooperation, should be grateful is not blame, The reason for the failure or their own, wrong in the director, wrong in the planning. There is a song to sing: life is unavoidable, ups and downs will be in the past, but also rely on their own success.
Life Review 100 Pro life. There is no smooth sailing, the course has a deviation, clenched to adjust the steering is, after all, there is a difference between the two sides, There is no terrible; no matter how rough road, the road is to go; life experience how much suffering, or to live. How the quality of life, and their past than in the future, when the meet will come, the life of the savings regret gone. And occasionally with the wrong, wrong on the wrong, it becomes the past, in frustration in the struggle, waiting for success in the struggle, in the efforts to get a better; past glory, it is the past, does not mean now or in the future, Do not mention then Yong. Gentleman "defeated not hungry, wins not arrogant", at the change does not panic, at the inverse chaos. Indulge in joys and sorrows among the better looking back, looking for happiness.
How much experience of human suffering, the new life is always not stop the pace of forward. Laugh, happy smile, laugh will bring you the beauty of life.
