Plastic is not the enemy against environment. Plastic is a kind of energy-saving material, it can replace other products to realize energy saving and reduce green gas emission. If not using plastics, the global energy would have been scarcer, air pollution would be more severe. This opinion gradually become the common sense for plastic industry.

 

However, industry insider also says that although plastic industry has a promising future, it also need to the more and more severe environmental problems causing by plastic bags and plastic products. Plastic associations in all countries think that encouraging to reuse plastic products and recycle waste plastic is the key point for plastic industry sustainable development.

 

Waste plastic recycling is an important way to turn waste into value and deal with ecological environmental pollution. As a measure for energy saving and environmental protection, waste plastic recycling has been attached much importance by every country.

Followings are world waste plastic recycling market current situation.

 

One, Asia

Japan is doing very well in waste plastic recycling. According to Japan plastic industry joint association, in 2008, Japan plastic recycling rate was as high as 76 percent. Recent years, other countries in Asian also pay more attention to waste plastic recycling and reusing. They all think that reducing plastic usage is not simply that government forbid plastic usage, what’s more important is to raise people’s awareness, develop a good habit and establish a complete recycling system.

 

Two, Europe

According to statistics by Europe plastic manufacturing and recycling group, in 2008 European waste plastic recycling rate was 54 percent. In 2009, Austria, Belgium, Denmark, Germany, Holland, Norway, Sweden and Switzerland waste plastic recycling rate all surpassed 82 percent.

According to Britain plastic joint association reported in July 2010, Britain expanded polystyrene package, namely EPS, recycling rate is one out of three. According to two industry associations, 2011 European PET bottle recycling rate rises by 9.4 percent, reaching 1.59 million tons.

Three, America

2009, among PET, HDPE and other plastic products, plastic bottle recycling rate in America has reached 99.7 percent.

 

Plastic problem has to be solved under every citizen’s efforts to improve our environment.

PE Introduction

Polyethylene, PE for short, is a simple structured macromolecule organic compound. It is now the world’s most widely used high polymer material, which is made of vinyl polymerization. PE is classified as LDPE and HDPE according to their density.

PE is insoluble in water, has very low water absorbency. Even in some chemical solvent such as methylbenzene and acetic acid, PE can only be dissolved a little when the temperature is over 70 degree centigrade.

However, PE pellets can be melting or solid between 15 and 40 degree centigrade. For its low water absorbency, uneasy to get damp and electrical insulation, it is very good construction material.

Physical and Chemical properties:

Appearance and shape: Flexible resin pellet or powder, white, wax smell.

Hazardous characteristics: cause burning and exploration when with strong oxidant.

Skin touch:Take off and isolate polluted cloths and shoes. Make sure medical workers know about PE protection knowledge.

Eyes touch: you should immediately wash at least two times once this stuff touches your skin and eyes.

Breathe in: move the person to some fresh air place and find a doctor.

In addition, PE is a recyclable material, making it a more popular material.

 

Wal-Mart Joins Hand with JNJ to Enlarge Plastic Film Recycling

Recently, Wal-Mart Canada joins hand with Johnson and Johnson together with Canadian plastic industry association to promote recycling program facing the consumers. The recycling program does not only aim at shopping plastic bags, but also including other forms of plastic bags and plastic films.

Wal-mart Canada franchise has always recycling shopping plastic bags, and now they are planning to enlarge the recycling variety further.

JNJ takes part in this program, and is now in the stage of trying. As is known to us all, JNJ in the manufacturer of Ziploc brand plastic bag.

blog15001

Retailer, manufacturer and trade groups will officially public this program in August.

Fundamentally speaking, we recycle films or plastic bags of all kinds, says the Canadian plastic industry association sustainable development vice president Krista Friesen, we are very exciting, because this is the first time that plastic recycling program tripartite cooperation. Besides, this is related to Canadian domestic public construction, providing recycling approach to all citizens and this is very good.

In the future months, Canadian plastic industry association will audit the recycling program, deciding what kind of plastic can be put in the recycling bin. The association will provide storage support after the program carries out.

Formerly, recycling bins highlights the functions of shopping bags, now the recycling bin reminds people that various plastic bags and films are recyclable, including bread bag, dry clean bag, newspaper bag, food package, commodity package, and box package film.

Of course, Ziplock zipper bag and other food storage is also recyclable.

But one key point of this program is that recycled material must be clean and dry.

If the collected material is clean, recyclers would accept. From our point of view, we hope to improve Canadian material recycling rate. Says Friesen.

We will try our best to put more clean material into recycling network. Our standpoint is out of these materials’ high value, the public also hope to deal with these materials properly, and we just hope to provide such infrastructure.

Proper Waste Plastic Recycling Management Can Save Four Billion Every Year

Recently, the first UN environment is open in Nairobi, according to the report of “Estimate Plastic Value”, by good plastic management such as plastic recycling; consuming industry can be saved by four billion dollars every year.



blog14002

The UN Environment Program 2014 Yearbook reviews the top ten most urgent environmental problems, including plastic waste in the ocean. Meanwhile, the Environment Program supported report “Estimate Plastic Value” found that plastic consuming in consuming industry expends natural capital as much as 75 billion dollars.

 

The report shows that greenhouse gas emission by plastic raw material extract and management exceeds 30 percent of the natural capital, but ocean pollution is the highest cost of downstream cost.

 

Plastic waste in the ocean come from garbage bins, poor managed refuse landfill, tourism and fishing industry. Some materials will sink under the sea; others will flow with the ocean far away, polluting the coastline and accumulating in large scales.

Plastic waste severely pollutes the natural environment, sea turtles will get disease or even die when swallow the plastic waste; plastic waste might also entangle dolphins and whales, damage their habitat. In addition, plastic waste may also produce chemical pollution, plastic scrap will lead to invasion of alien species, and damage much national tourism and fishing such as pollutes the beach and destroys the fishing gear.

The UN Environment Program 2014 Yearbook gives special attention to micro plastic, that is plastic granules whose diameter is less than five mm produced during manufacturing. Micro plastic is very easy to be swallowed by marine organism by mistake. These wastes are difficult to be filtered during sewage disposal, and will directly be discharged into rivers, lakes and oceans. Groups of marine organism have been found gathered around micro plastic in many areas in North Atlantic Ocean. These micro plastic can spread harmful microbe, causative agent, algae and other species.

Plastic Disclosure Program supervisor Andrew Russell emphasizes that companies and enterprises need to take plastic footprint into consideration just as they consider carbon footprint, water footprint and forest footprint.

 

 

13 Reference Standards of Choosing PE Plastic Package Film

PE plastic package film is processed by choosing thin PE film  pellets, through blown up or curtain coating, processed into film-shaped fixed form with about 0.002-0.3 thickness. With the popularization of plastic package products, PE plastic package film occupies a larger market share, and is widely used in hardware machine, auto parts, express delivery, furniture, household appliance, food, medicine, textile, chemistry and other industries, these products all bring great convenience to our daily life.

Different kinds of plastic package films have different properties. When choosing these plastic package films, we need to choose according to the film’s basic properties and functions. Mainly take special needs such as product protection, promotion, adaptability and application into consideration. There are following 13 reference standards:

 

One, protection function

As product package, plastic film’ protection function is the most important and most fundamental function. If plastic film has no protection capability, resulting in product damage or devaluation, it loses its value as package material.

 

Two, mechanical protection

Prevent packaged product from leaking or outside substance from damaging or polluting product. Performance index which directly indicate plastic film mechanical protection is film mechanical strength such as tensile strength, tearing strength, anti-puncture strength.

 

Three, good weld strength

Weld strength is also a necessary condition for plastic film to stably protect product. If weld strength is not enough, the weld joint will become a deadly shortcoming for the plastic film bag. Protection function will lost due to weld joint fracture.

 

Four, barrier property

Barriers property refers to the function of stop oxygen, carbon dioxide, nitrogen, fragrance, vapor and other substances from infiltrating. Product display effects is intimately related to plastic film’s light transmittance, haze, glossiness, antistatic property and so on, enough light transmittance and haze should pay more attention.

Five, light transmittance and haze

Light transmittance and haze are important indicators deciding packaged product visibility and definition, which is greatly related to product display effect. The higher the light transmittance is, the better; while the higher the haze is, the definition is worse.

 

Six, glossiness

Glossiness refers to plastic film’s light reflect ability when lighted.

 

Seven, antistatic property

With the violent development of electronic industry, circuit board integration gets higher. Application of antistatic property can avoid static destroying integrated circuit.

 

Eight, fine smoothness

Good smoothness is in favor of package film moving smoothly on the manufacturing line, avoiding big resistance results in damage during moving.

 

Nine, resistance to elevated temperature

Low temperature resistance and high temperature resistance are common considerations. For example, refrigeration, especially plastic film used in frozen food, excellent low temperature resistance is needed.

 

Ten, sanitation property

When packaging food or medicine, we must choose plastic film of great sanitary property to make sure the packaged products won’t be polluted.

 

Eleven, air impermeability

Good air permeability can effectively stop inside and outside air from exchanging, this is necessary for most products.

 

Twelve, moisture resistance

Good moisture resistance is an effective measure to protect product, ordinary plastic film moisture resistance gets better when its thicker worse when temperature gets lower.

 

Thirteen, oil resistivity

For oily food such as sausage, the package film must be oily resistivity; otherwise it will influence the product quality.

PET Chemical Properties and Grade

PET Chemical Properties and Grade

PET’s success in application to beverage package material dues to its tenacity and transparency, orientation capability, excellent economy value and high efficiency bottle process technology.

PETpropertyandgrade1PETpropertyandgrade2

PET beverage bottle has the advantages of light weight, uneasy to break, recyclability and great airtight property. Fully filled 2 liter PET beverage bottle is 24 percent lighter than glass bottle, while empty PET bottle’s weight is one out of ten’s weight of the same type glass bottle. All of those advantages enable labor, energy, and cost saving during all steps from manufacturer to consumer.

One, PET Chemical Propertie

 

PET applied to beverage bottle is composed of TPA. Purifying terephthalic acid or react with carbinol to produce DMT or further oxidation of TPA. Another primary material of PET is ethane, ethane is transferred into EG after reaction. PET is a polycondensate produced from DMT and EG constant reactions.

Usually the PET resin melts dowm at 480F, but high-crystallized PET meltdown raise to about 520F.

Two, PET Special Grade

Stretch blow molding grade PET provides pure green and yellow PET. Polymer in reactor won’t bring side influence on property and improves color distribution. All kinds of different intrinsic viscosity resin can be gained. PET copolymer has a low crystallization speed which make it possible to produce high quality beverage bottle under available conditions.

This material owns the merits of excellent melt strength and low crystallization speed, so it can be simply processed by proper extrusion blow molding equipment. Other polymers are continuously introduced to improve and meet new demand in applications.

 

Frequently-used Plastics Property Comparison

Since synthetic materials have extraordinary properties, they are widely used in package field. Most plastic can be applied to beverage and food package and plastic bottle manufacture; among which cheap polyolefin is the largest used material.

 

Frequently-used plastics are polyethylene, PVC, polypropylene, PET and polycarbonate. Polyethylene/ PE is the world’s largest produced synthetic resin and is also the most consumed plastic package material, occupies about thirty percent of package material. LDPE has good transparency, is soft, good elongation, and is better than HDPE in quake resistance and low temperature resistance. It is largely used in all kinds of packages, but as food package material, it has its disadvantages are quite obvious.

Typical products are polystyrene foam plastic, rigid polyurethane foam plastic, PVC foam plastic and other kinds of foam plastic. These materials can be applied as heat-resistance material, interlayer material, packaging material, noise insulation and anti-quake material, construction material and so on.

 

Features of rigid foam plastic:

 

First, rigid foam plastic has low volume weight which can reduce package weight, thus help saving transportation cost.

 

Second, rigid foam plastic material has excellent absorbency for strike and shaking energy. If applied as quake reducing material, it can greatly reduce products damage.

 

Third, rigid foam plastic has high adaptability to temperature and humidity change which meet general package requirements.

 

Four, low water absorption rate, low moisture absorption and stable chemical property. It won’t lead corrosion to packaged product and has strong tolerance to acid, alkali and other chemicals.

 

Five, rigid foam plastic has low thermal conductivity which can be used in heat insulation package such as ice creams, fast food containers and fish tank.

 

Six, easy to shape and process and can be manufactured by mould, extrusion, injection and other ways. And it is easy to be twice manufactured, for example, when heated foam plastic can be processed to fast food containers.

 

For all these features, rigid foam plastic has a wide scope of applications and can be reused. So waste foam plastic is recyclable. Recycled foam plastic can be processed to pellets and make other products such as picture frames.
