First of all, performance can not be completely replaced, such as meat, seafood and other oily goods, using paper bags and cloth bags can not solve the problem well. Secondly, excessive use of paper bags will lead to excessive deforestation, damage the ecological balance, and cause catastrophic and unacceptable harm to the environment.

　　1.研究開發(fā)可回收利用的綠色包裝材料。包裝廢棄物法規(guī)因地而異，但有一個共同的原則：鼓勵少用原材料。在包裝設(shè)計上應(yīng)盡量使用同一材料、可分離可共存的材料并趨向于使用結(jié)構(gòu)簡單、容易循環(huán)再生的材料。在滿足包裝功能的前提下，盡量減少垃圾的產(chǎn)生量，從而呈現(xiàn)包裝薄膜輕量化發(fā)展趨勢。

　　1. Research and develop recyclable green packaging materials. Regulations on packaging waste vary from place to place, but there is a common principle: to encourage less use of raw materials. In the packaging design, we should try to use the same material, separable and coexistent material, and tend to use the material with simple structure and easy recycling. On the premise of satisfying the packaging function, reduce the amount of garbage as much as possible, so as to present the development trend of lightweight packaging film.

The varieties researched and developed in China have covered photodegradation, photodegradation, photodegradation, high starch content type photodegradation, high calcium carbonate filled type photodegradation, total biodegradation and other categories; the application of degradable plastic products in packaging has spread to ordinary packaging film, shrink film, shopping bag, garbage bag and so on, which has played an active role in improving environmental quality Use. In order to protect the ecological balance, it is urgent to study the fully biodegradable plastics, especially the high-quality and low-cost biodegradable plastics filled with edible powder or inorganic minerals.

　　4.研發(fā)焚燒回收熱能或采用煉鋼爐再利用塑料廢棄物的研究開發(fā)焚燒回收熱能是塑料廢棄物再資源化的一個主要手段，也是治理塑料廢棄物的更現(xiàn)實的選擇。今后應(yīng)研究開發(fā)塑料垃圾處理提供熱能的有關(guān)設(shè)備，設(shè)計出使用更為簡便、壽命更長、更低的設(shè)備，以加速我國焚燒回收熱能和利用煉鋼爐再利用塑料廢棄物的研究開發(fā)。

　　4. Research and development of recycling thermal energy by incineration or recycling plastic waste by steel-making furnace; recycling thermal energy by incineration is a major means of recycling plastic waste, and also the most realistic choice for the treatment of plastic waste. In the future, it is necessary to research and develop the equipment related to the thermal energy provided by plastic waste treatment, and design the equipment with more convenient use, longer service life and lower price, so as to accelerate the research and development of recycling thermal energy by incineration and recycling plastic waste by steel-making furnace in China.

　　5.可食性薄膜可食性包裝膜是以天然可食性物質(zhì)(如多糖、蛋白質(zhì)等)為原料，通過不同分子間相互作用而形成的具有多孔網(wǎng)絡(luò)結(jié)構(gòu)的薄膜。如殼聚糖可食性包裝膜、玉米蛋白質(zhì)包裝膜、改性纖維素可食性包裝膜及復(fù)合型可食包裝膜等，可食性薄膜可應(yīng)用于各種即食性食品的內(nèi)包裝，在食品行業(yè)應(yīng)具有巨大的市場。

　　5. Edible film edible packaging film is a kind of film with porous network structure, which is made of natural edible materials (such as polysaccharide, protein, etc.) through the interaction between different molecules. For example, chitosan edible packaging film, corn protein packaging film, modified cellulose edible packaging film and composite edible packaging film, etc., edible film can be applied to the inner packaging of various ready to eat foods, which should have a huge market in the food industry.

　　6.水溶性塑料包裝薄膜水溶性塑料包裝薄膜作為一種新穎的綠色包裝材料，在歐美、日本等國被廣泛用于各種產(chǎn)品的包裝，例如農(nóng)藥、化肥、顏料、染料、清潔劑、水處理劑、礦物添加劑、洗滌劑、混凝土添加劑、攝影用化學(xué)試劑及園藝護(hù)理的化學(xué)試劑等。

　　6. Water soluble plastic packaging film as a new green packaging material, water soluble plastic packaging film is widely used in the packaging of various products in Europe, America, Japan and other countries, such as pesticides, fertilizers, pigments, dyes, detergents, water treatment agents, mineral additives, detergents, concrete additives, photographic chemicals and gardening care chemicals.

　　7.進(jìn)行循環(huán)經(jīng)濟(jì)型塑料發(fā)展相應(yīng)的對策、法律、法規(guī)和制度的制訂和實施辦法的研究。目前，我國固體塑料廢棄物分放的設(shè)施在上海市已經(jīng)出現(xiàn)，但仍有很多人隨意投放。相當(dāng)多的地區(qū)、部門和企業(yè)，表現(xiàn)出只顧眼前利益的短期行為。

　　7. Focus on the research on the corresponding countermeasures, laws, regulations and systems for the development and implementation of circular economy plastics. At present, China's solid plastic waste separation facilities have appeared in Shanghai, but there are still many people who drop them at will. A considerable number of regions, departments and enterprises have shown short-term behavior of focusing only on immediate interests.

　　8.CT材料日本化學(xué)公司經(jīng)過10年的努力，已研制成功符合環(huán)保原則的食品包裝容器專用塑料CT。CT不僅耐高溫，還有一個更突出的優(yōu)點(diǎn)，就是它的功能與俗稱"泡法沫塑料"的PSP塑料制品相仿，而其體積只相當(dāng)于后者的1/4。這樣在回收時避免了因體積龐大而產(chǎn)生的諸多麻煩，并為對環(huán)境的負(fù)面影響創(chuàng)造了極有利的條件。

　　8. After 10 years of efforts, CT materials Japan Central Chemical Company has successfully developed a special plastic CT for food packaging containers in line with the principles of environmental protection. CT is not only resistant to high temperature, but also has the most outstanding advantage, that is, its function is similar to PSP plastic products commonly known as "foam plastic", and its volume is only 1 / 4 of the latter. In this way, many troubles caused by large volume are avoided in recycling, and favorable conditions are created for eliminating the negative impact on the environment.

　　9.新型高阻隔性塑料包裝材料新型高阻隔性塑料在國外已廣泛應(yīng)用，國內(nèi)也已引進(jìn)這項技術(shù)。使用高強(qiáng)度高阻隔性塑料不僅可以提高對食品的保護(hù)，而且在包裝相同量食品時可以減少塑料的用量，甚可以重復(fù)使用?，F(xiàn)在國內(nèi)常用的高阻隔性材料有鋁箔、尼龍、聚酯、聚偏二氯乙烯等。隨著食品對保護(hù)性要求的提高，阻隔性更好的乙烯、乙烯醇共聚物、聚乙烯醇等也開始應(yīng)用。

　　9. New high barrier plastic packaging material new high barrier plastic has been widely used in foreign countries, and this technology has been introduced in China. The use of high-strength and high barrier plastics can not only improve the protection of food, but also reduce the amount of plastic when packaging the same amount of food, and even can be reused. At present, the commonly used high barrier materials in China are aluminum foil, nylon, polyester, polyvinylidene chloride, etc. With the improvement of food protection requirements, ethylene, vinyl alcohol copolymers and polyvinyl alcohol with better barrier properties have also been applied.
