Due to the non-degradability of foamed tableware, the environment has a great impact, and there are certain difficulties in comprehensive recycling. In order to conceive the overall situation of environmental protection, the State Economic and Trade Commission issued the No. 6 Order, which clearly stipulates the complete prohibition of the production and sale of disposable foam tableware in China, and puts forward the basic requirements for replacement products, namely, it is easy to recycle and easy to degrade. The new national standards for degraded tableware were promulgated and divided into two categories, five categories, including “light/biodegradable polypropylene tablewareâ€, “pulp molded tablewareâ€, “cardboard laminating tablewareâ€, “full starch tablewareâ€, New food and beverage appliances such as "plant fiber synthetic tableware". In order to ensure the safety of the new tableware for the human body, correctly guide the research, development, promotion and use of disposable degradable environmental protection tableware, according to the requirements of the National Technical Monitoring Bureau and the use of various lunch boxes in recent years in the country, In the past three years, we have learned from the research and development of various new fast tablewares. Under the current market conditions and technical conditions of domestic disposable tableware, it is most feasible to promote the use of degradable polypropylene lunch boxes (PP). The main advantages are as follows:
1: The raw materials are widely sourced and the quality is stable, and the domestic market can fully meet the requirements.
2: The product quality can meet the strict requirements of the Ministry of Health on polymer food packaging containers and the one-off degradable catering has indicators, and the degradation fully meets the national standards.
3: The price of qualified products is fair, lower than paper products (about 0.006 yuan / gram), easy to promote and apply.
4: The product is safer and healthier, can be used in the microwave oven, can eat hot food below 120 degrees without the overflow of harmful substances, which is not possible with other disposable tableware.
5: The discarded lunch boxes are easy to recycle for secondary use, and no one needs to be forced by the government to pick them up. The amount of landscape pollution is greatly reduced.
6: The degradation rate in the field is fast, and it can be broken and powdered in normal temperature environment for 1-2 months. The molecular weight is greatly reduced (more than 80%, the molecular weight is less than 10,000% and more than 20%), and it is easily removed by the environment after being corroded by microorganisms. Na, no secondary pollution problems.
7: The investment is small and the output is high. All equipment investment is calculated by producing 10,000 to 120,000 products per day. If one-step production equipment is used, according to different types of equipment, only about 12 to 220,000 yuan is needed, and the annual output of the lunch box can reach 2,500. ~36 million, the product adapts to the market ability.
8: Can produce all kinds of thermoformed plastic products (such as cold drink cups, yogurt cups, ice cream cups, tofu boxes, snack boxes, vegetable plates and medicines, light industry, textiles, travel, toys, etc.), compared with paper tableware production lines The same investment output is three to five times higher.
Second, the production process profile (taking double-layer composite equipment as an example)
This kind of equipment is currently a more advanced and fully functional composite extrusion molding machine in the domestic one-step tableware forming machine. It can integrate extrusion, plastic, positive pressure forming and negative pressure forming into one, high-speed continuous operation, realizes all the processing procedures of automatic continuous extrusion, drawing and forming of the whole machine, improves production efficiency and saves energy. As long as the material is added to the hopper, the whole process automation from raw material to product forming to cutting can be realized, and the high-quality double-color two-color composite tableware and packaging products can be finally obtained. The products have the advantages of good finish, moderate hardness, multiple colors, low cost, etc. Due to the positive pressure forming system, this machine can also process 80mm special depth products. The products are widely used in supermarkets, distribution centers, schools, fast food restaurants, medicine, food packaging and other industries for use and export trade.
Third, the main equipment configuration
One 65/80 extruder, forming machine, cutting machine, vacuum pump, mixing machine, pulverizer, etc.
Fourth, the process
PP resin + degradation masterbatch + calcium carbonate filler - melting - extrusion - pull tab - forming - cutting - packing
V. Investment and benefit analysis
1: Main products: disposable snack boxes, clean dishes, bowls, disc chess format trays, dried fruit packaging trays, water cups and other products. Suitable for the production of PP, PE, PS, PVC and other materials.
2: Production energy: The production capacity of single machine is 120,000 pieces / 22 hours, the annual output is 36 million pieces / 10 months, and the annual use of raw materials is about 600 tons.
3: Equipment investment: 220,000 yuan (currently automatic price 178,000 yuan, semi-automatic price 162,000 yuan)
4: Installed capacity: 65 kW (using power 35 kW / hour)
5: It is required to produce 150 square meters of factory buildings, 100 square meters of finished product warehouse and raw material warehouse, and other housing.
6: 5 workers are required to work in a single shift.
7: The activity fund is 200,000 yuan.
5. Calculation of production cost and profit: (calculated as 16.5 grams of 400 ml lunch box)
1: PP raw material 47% (470 kg) × 6.8 yuan / kg = 3196 yuan
2: Degradation masterbatch 0.2% (2 kg) × 25 yuan / kg = 50 yuan
3: Calcium carbonate filler 54% (540 kg) × 1.8 yuan / kg = 978 yuan
Comprehensive material cost 4224 yuan / ton
4: The electricity consumption rate is 35 kW / hour (including the consumption of auxiliary equipment), the production time of ton of materials is 11 hours, and the power consumption is 385 degrees × 0.66 yuan / kW = 254.1 yuan.
5: Equipment depreciation is calculated in six years, the daily amount is 100.46 yuan, and the ton of materials is equivalent to 50.3 yuan.
6: Labor 8 people × 20 yuan = 160 yuan / ton (12 hours, including staff members).
7: Sales business office and other costs 100 yuan / ton
8: Taxation (calculated as 6% of turnover) = 420 yuan / ton
9: Governance office staff use 8 people × 50 yuan / day = 400 yuan, ton of materials equivalent to 200 yuan.
10: tons of raw materials and products transportation cost 200 yuan / ton
11: Packing capacity of 1200 / box, a total of 50 boxes × 6 yuan = 300 yuan (including plastic bags)
The comprehensive cost per ton of material is 5908.4 yuan
Production of 28,000 double-color composite tableware per ton of material, the domestic minimum ex-factory price of 0.11 yuan / only (market price is not less than 0.14 yuan / only) = tons of sales of 6380 yuan
Tons of sales of 6,380 yuan - comprehensive consumption of 5908.4 yuan = ton of net profit of 471.6 yuan
Annual use of raw materials 600 tons × 471.6 yuan = profit 282960 yuan
The unit is calculated according to the 10-month production period, using 600 tons of raw materials and achieving a profit of 282,960 yuan.
