Domestic food production and application of plastic flexible packaging errors

Import cooking temperature; In addition, PET film hardness itself, very high, the air exhausted is not easy, although there are excellent barrier properties, but reduced the bactericidal effect of cooking, it is only to do a PET film vacuum packaging, can not make cooking and packaging . PET film with a film to replace PA or increase production of cooking and packaging of the four cooking composite PET packaging films, can only reduce costs,[link widoczny dla zalogowanych], but no PA (nylon) / AL (metal foil) / CPP (cast polypropylene) composite three cooking effective sterilization packaging,[link widoczny dla zalogowanych], long shelf life. Paper-plastic film packaging is not necessarily environmentally friendly paper-plastic film packaging is paper and plastic composite packaging, usually on paper tape PE and PP composite made of composite processing technology (combined with a dry way higher processing costs.) Paper and plastic packaging plastic packaging than good ventilation, poor water resistance and barrier,[link widoczny dla zalogowanych], and therefore need to release and moisture commonly used in the packaging of goods, such as camphor tablets in China Packaging 2009/755 packaging, moisture-proof agent (drying) and other packaging. After only a composite of paper before sealing plastic bag, but not after the recovery of composite plastics or natural decomposition, in addition, the production of raw materials, paper, wood, heavy use is a waste of natural resources. Therefore, some people think that paper-plastic packaging plastic packaging more environmentally friendly,[link widoczny dla zalogowanych], in fact, is unreasonable. The seeds, dried fruit with a paper-plastic packaging of food is reasonable and very worth exploring. Food consumption of plastic flexible packaging applications errors: In daily life, as consumers know very little knowledge of plastic packaging is often not used correctly, this person's health and lives of potential hazards. PE (polyethylene) film packaged food should not be packaged with its vegetable fried foods, hot milk and serve leftovers, very unscientific, into the microwave is harmful. In addition, color PE film bag, such as color vest bags, color bags, black trash bags full bloom Dengjun not food, because of which put a lot of Yen plus masterbatch and recycled plastics, can contaminate food. PVC (polyvinyl chloride) film should not be heated PVC cling film food packaging food packaging can not be heated, because the heated PVC film after film preservation in the blur (plasticizing) agents will precipitate and contaminate food. In addition to PET (polyester), PA (nylon) and other polar film, other plastic film packaging will contaminate the food when heated, harmful to human health. The PVC (polyvinyl chloride) film made of plasticized, tensile properties, softness, resistance to aging will be greatly enhanced, often used to make synthetic leather, table cloth, blankets and quilts, and electrical hardware tools packaging However, the oil must not be used to hold food. Recently, the China Printing Equipment Industries Association and organized by Beijing Institute of digital printing machinery inkjet printing technology and development held in Beijing. Association leaders, industry experts and more than twenty domestic and foreign industry's top manufacturers attended the meeting on the current world and China Digital and inkjet printing technology status and prospects were discussed and successful communication. The meeting chaired by the Secretary-General of Association of Xu Jinfeng, Wang Demao made the opening speech, vice president, vice president of Pu Jialing professor of Beijing Printing, China Printing and Digital Printing Equipment Industries Association branch of the Secretary-General Zhao Wei, Chen Yi, Beijing Institute of Printing Machinery Ying, respectively, from the Chinese digital printing market, from the user application point of view about digital printing, digital printing from a media point of view three aspects of the market made a keynote speech, and made with the manufacturers on behalf of the depth of communication and discussion. Meanwhile, in order to promote China's development of digital and inkjet technology, and promote digital and inkjet printing technology for professional audience out of China Packaging 2009 / 7 for the advanced and efficient digital and inkjet printing equipment, the equipment suppliers in the financial crisis in the inspired, efforts to overcome the difficulties caused by the crisis, boost the confidence of overcoming the crisis, go digital and inkjet printing industry development needs, China Printing Equipment Industries Association and the Beijing Institute of Printing Machinery co-sponsored by the China Digital and inkjet printing technology exhibition (D-Print) will be held in August 2010 3113-9 2 May in Beijing China International Exhibition Center. Bao-Chi Association Deputy Secretary-General introduced the event-related information, business representatives also shared a common field of digital inkjet printing with advanced technology and market demand, and hope through our efforts and the common prosperity of the digital inkjet market. According to information issued by General Administration of Press and Publication, 2009, the output value of China's books and 75 billion digital printing, traditional printing output value of 600 billion yuan,[link widoczny dla zalogowanych], production value of digital printing over traditional printing output. In 2010 as the country's economic development, the printing industry will also usher in the revitalization of the industry and the economic recovery, digital printing will also be an even greater development!
