Plastic wrap, to put it bluntly, is a kind of plastic film. Because of its high density, it can isolate moisture, and it was first invented by the United States to wrap bullets against moisture.

Later, it was discovered that it can not only isolate moisture, but also prevent direct contact between food and air, bacteria and other things, so that food is not contaminated, so as to achieve the purpose of keeping food fresh.

As a result, this cheap preservation product has since become an instant hit, and has done its part for people's lives and white pollution.

Song Mu hadn't yet reached the realm of considering protecting Mother Earth, and she saw that the other two were full of question marks, so she first introduced the plastic wrap to the two of them, and then once again exerted her ability to lie to herself.

"Didn't I go to Midi to receive the award, I was invited to live in Mr. Liu Difu's house at that time, and I saw that everything he ate was wrapped in a kind of film, so I asked curiously. Mrs. Liu was very hospitable, and when she saw that I was curious, she introduced me carefully. ”

Her explanation can be said to have a beginning and an end, Shen Chang and Chen Zhanpeng didn't doubt her originally, but they were even more convinced at the moment.

Chen Zhanpeng said while thinking about it: "According to the situation you described, I think this plastic wrap is much thinner than plastic film.

"The most important thing is that the hand can tear and at the same time the ductility is quite high, and there is a certain adhesion between the utensils and the plastic wrap itself, which is still relatively difficult to do. Even if the main material is polyethylene, the additives are definitely not the same as mulch.

"But if you can figure out the additives and proportions, with the role of this plastic wrap, it's really easy to make money."

Shen Chang also agreed with Chen Zhanpeng's judgment: "Xiao Mu also said that polyvinylidene chloride can be used as the main ingredient in addition to polyethylene, but I think that no matter what kind of main ingredient it is, it is difficult to achieve the kind of properties she said, and the main additives are a problem."

"If you want to have this effect, polyisobutylene, low-density polyethylene, and glycerol are estimated to be indispensable, but the specific ratio has to be studied.

"Since you both think plastic wrap is a good project, I'll go to Lianhua tomorrow to resign, and I'll start experimenting after we complete the handover formalities. If it really doesn't work, Brother Chen, let's go to the United States together, I don't believe that we can't get this technology back. ”

After Shen Changgang finished planning the future enthusiastically, Song Mu weakly raised his hand: "I know that the main plasticizer added to PV plastic wrap is called DEHA, if you really can't help it, you can try it in this direction, the premise must be when you really can't help it." ”

"PV plug? DEHA？ PVC and diethyne? Shen Chang became more and more surprised by what Song Mu knew: "This is also what Mrs. Liu told you?" Is she my peer? ”

"Ahem, someone is a housewife!" Song Mu was almost choked by Shen Chang's words, and she threw the pot out again with a roll of her eyes: "It's because I'm a housewife that I care very much about the food safety at home."

She said that the United States used to use PV plug cling film, but recently scientists found that when PV stopper cling film is heated or in contact with grease, the DEHA inside is easy to run out, and DEHA seems to be harmful to the body, so the home is now using P plug cling film......"

The information that Song Mu said has been reported on the news in later generations, and it has all been verified by scientists. She wasn't sure if the current scientists had discovered these problems, but she believed that Shen Chang and Chen Zhanpeng shouldn't have too much to do with them. Wrap.

Sure enough, as she expected, Shen Chang did not doubt the source of these news, and he was entangled in the question in his words: "Does it mean that it will be precipitated due to high temperature and grease?" That's something to be aware of. Although we want to make money, we can't make that kind of money with a bad conscience. ”

"Indeed, if it is harmful to people, we should try not to use it as a last resort." Chen Zhanpeng nodded, but he didn't say anything completely, and after a moment of silence, he continued: "But if we really can't do it, I'm afraid we can only develop in this direction."

"When the time comes, mark it clearly on the packaging, and use eye-catching large characters to explain that our plastic wrap can't be heated or can't be wrapped in grease, so there should be no problem."

Song Mu was very satisfied with the method proposed by Chen Zhanpeng, which made her more sure of the correctness of the decision to recruit Chen Zhanpeng to give Shen Chang a hand.

Song Mu was worried about Shen Chang's tendons, so he reminded him again: "Brother Chen is right, if you really can't do it, you still have to experiment in this direction." After all, from now on, if you don't work for others again, there will be a group of people under your command to eat. If the factory doesn't work for a day, they have to drink the northwest wind for a day. You have to figure out this cause and effect. ”

Shen Chang really didn't want to use a PV plug, but after Song Mu's reminder, he also realized the problem. sighed helplessly and said, "That's the same reason." Brother Chen, we have inventory of main materials and related additives in our warehouse, right? ”

After getting Chen Zhanpeng's affirmative reply, he compromised: "Then after completing the formalities, I will start the experiment directly, PE and PV plug two lines to experiment together, PE can become we will make PE plastic wrap, PE can not become and make a usable PV stopper cling film, let's start to produce PV stopper cling film, PE cling film and I will continue to research later." ”

"Okay."

"Yes."

Song Mu and Chen Zhanpeng responded at the same time.

The key issues and business have been discussed, and the three people at the table began to eat, drink and chat again, and the meal lasted until almost nine o'clock, when Song Mu and Shen Chang came out of Chen Zhanpeng's house. Although the meal lasted for a long time, the three of them only drank old baijiu, and they were basically not drunk.

Shen Chang drove to the city, he finally took the first step towards his dream, and his mood was indescribably happy. Song Mu sat in the co-pilot, looked at Shen Chang's radiant side face, and couldn't help but laugh silently......

Early the next morning, Shen Chang was not in a hurry to go to work. He made a call to the factory, and after reporting that he was ready to resign, he first went downstairs to Song Mu's house to pick up Song Mu, and the two went to the bank again.

Since the large amount of accounts had not yet been completed, Song Mu found the master who did the business yesterday, and after explaining the situation in detail, the old man agreed to her request to handle it for her.

With the help of the master, she first transferred part of her money to the previous passbook, and set aside 500,000 yuan to open a new passbook.

After leaving the bank with a thousand thanks, Song Mu handed over the new passbook to Shen Chang, and after giving him a few key points, the two temporarily separated at the door of the bank.

Shen Chang wants to go to Hualian to hand over the resignation letter and go through the process of factory transactions, while Song Mu wants to be a fortune boy......

"...... this?" Zhao Wende looked puzzled, looked at Song Mu, who slapped the passbook on the counter when he entered the door, and asked in a low voice.

Boss Zhao's video hall was unusual, it was obviously work time, several rows of benches in the screening room were full of people, and there were a few people standing against the wall without seats, and everyone was watching "Splitting the Mountain to Save the Mother" playing on the screen.

Song Mu didn't answer Zhao Wende's question, but teased with interest: "It's the first time I've seen you here." ”

"It's not you! I'm going to be a mess here! Zhao Wende looked so dissatisfied with this that he almost forgot to lower his voice: "Do you remember that little grandson last time?" After knowing that I have the limited edition villain you gave here, I brought his friends to visit every day.

"At first, I let them see it, but then I got annoyed that when more people came, I told them that I had to buy a ticket to get them out of the house. Good guys, these people not only didn't mean to leave, but came more diligently! ”

Song Mu pressed the twitch at the corner of his eye. moved, and asked with black lines: "...... That's how many people have changed? ”

"I didn't ...... it at that time" Zhao Wende seemed to remember something unpleasant to him, and Song Mu vaguely seemed to see the twitch in the corner of his eyes. Move: "I learned that I had no one here at noon on the day you won the award, so I turned out "Splitting the Mountain to Save the Mother" to take a look, so I didn't die Xiao Sun brought a few of his friends to push the door in......

"The movie theater just came out, and after knowing that I had a videotape here, it became like this......"
