Corrugated Box Making industries have been built in the country to package the industrial and non-industrial products. Their success depends on the performance of other industries.In this study, the influence of going Iran to the World Trade Organization on the Corrugated Box Making industries by field research methods which were investigated using questionnaires and evaluation matrix SWOT. The study results showed that due to the proximity of Iran to the supply sources of raw materials, consumption marked and labor costs, Corrugated Box Making industries could have a comparative advantage.Lack of integration construction of strategy management, guidance and surveillance in corrugated box making industry, educated work, educated work force and educable, International economic sanctions and proximity of Iran to the market supply of raw materials and consumption respectively, are the weaknesses, strengths, threats and opportunities of the Corrugated Box Making industries.

Flexographic printing is introduced as the most widely technology in packaging, but the quality of flexographic products is less than offset printing. One of the most important issues that threaten the quality of flexographic printing is weak adhesion of flexography ink to the substrate, especially polyolefin substrate. Organic silanes are environmentally friendly compounds that among properties of organic silanes can note to adhesion promotion, increasing resistance to water, Preventability that they are used to improve foor safety in the packaging, ink, paint, food and beverages industries. In addition to adhesion promotion, organic silanes can control and decrease of growth and adhesion of microorganism. Among of surfaces that treating by organic silanes can note to metals, plastics, glass, ceramics, rubber, polyester, polyurethane, polyacrylic, phenolic and melamine resins and polycarbonate. Optimization of formulation due to the high price of organic silanes is so matter. This paper review chemistry, features and applications of organic silanes in different industries. The purpose of this study is identification and distribution the opportunities and take advantage of organic silane to enhance adhesion in film packaging and decrease microbial adhesion.

Nowadays, the use of Nanoparticles due to the lightness, renewable, high surface area and high resistance in cellulosic composites and paper has been very important and by identifying and utilizing nanotechnology, tremendous opportunities has been located in the cellulose and packaging industry. Nano lignocellulose have interesting properties, such as renewable, low cost, very high specific surface area and resistance, chemical and mechanical stability, lattice structure and high cation exchange capacity factors. According to the packaging industry aims to improve the properties of paper and packaging cardboard, use of eco-friendly product and also low price seems necessary. Use of NFC to strengthen the paper and cardboard used in the packaging industry is not economy, because these products are mostly dark in color (brown) and are required to use Nano fibrillated cellulose (NFC) containing pure cellulose is bleached. So use of Nano lignocellulose fibrillated (NFLC) instead of Nano fibrillated cellulose (NFC) in coating of paper and paper board used for the packaging industry leads to reduce costs of raw materials, energy consumption and production (bleached and Homogenizing) of this substance.

This paper demonstrates consumption capability for wood-based xylan derivatives; nano fibrillated celloluse, mineral pigments & its nano particles and biodegrable polymers to be used in coating paper applications. Extraction and purification of pure xylan from bleached kraft pulp, preparation of nano fibers from woods, minerals pigments and new biopolymers such as poly-3-hydroxybutyrate (PHB) and polylactic acid (PLA) are described as a part of the production of coating suspensions. Also afficient derivatization as water soluble derivatives were achieved and promising results were obtained in primary application tests as a coating component in barrier coatings on board and as a binder component in pigments of coating. With the best suspensions coating, the barrier properties were better than with a commercial polymer coating, while oxygen permeability was roughly one third of that for a polyethylene terephthalate (PET) coating. Likewise, optical properties, printability and mechanical resistances have compared to the references coatings and commercial paperboards. In many cases, the mechanical properties such as resistance agains folding, tensile, burst and tear are improved.

Food packaging plays an important role in protecting and containing food through manufacture processes, Control, storage, handling and then delivering to customer. Innovation in food packaging industry cause to enhance the quality of foods, make them desirable for costumers, and award them biodegradable properties. Today, Nanotechnology applications in food industry include: encapsulation and delivery of substances in targeted sites, Entering antibacterial nanoparticles into food, Identifying pollutants, improved food storage and so on. Nano food materials packaging may extend food life due to high barrier packaging, improve food safety, alert consumers that food is contaminated or spoiled, repair tears in packaging, and even release preservatives to extend the life of the food in the package. Electro spinning is one of the nanostructured material fabrication techniques that, by using electrostatic forces for producing polymer, ceramic and composite fibers with a diameter ranging from micrometers to nanometers has become to a simple method. Resulting electro spun Nan fibers layers, duo to unique properties such as high specific surface area and porosity, are useful structure in a variety of applications including food packaging industry. Therefore, electro spinning is a promising method for producing active and intelligent food packaging. This paper summarizes the recent progresses in electro spun Nan fibers applications in food packaging industry.

Today's applying biodegrade able packaging such as edible coatings and films have attracted greater attention due to having natural products and lack of environmental pollution. Carbohydrate and proteins create a network responsible for good mechanical properties, but their inherent hydrophilic nature makes them a poor barrier for water vapor transfer. On the contrary, lipids have excellent water vapor barriers because of their hydrophobic character, but films made from lipids alone have poor mechanical properties. Therefore, with combination of these two materials, the produced composite film, has desirable properties. A composite film can be produced as either a bi-layer or a stable emulsion. Therefore, composite edible films have better moisture-barrier properties and also, due to the improved mechanical properties, they create better protect from food. So, the shelf life of food will be increased. In this review, has been focused on the preparation techniques, properties and advantages of composite edible films relative to one-layer edible films.

It is necessary to monitor the quality and corruption of fresh meat products, with the aim of reducing the incidence of diseases and reduce of food waste throughout the supply chain to meat; However, Traditional packaging systems are able to provide slightly services in the monitoring of the supply chain. the new intelligent packaging systems in order to monitor the quality of meat-packing or the environment of its around, are progressing towards to provide innovative packaging solutions in the production and supply of meat products. As today, the different types of commercial intelligent systems such as time-temperature, Integrity, Freshness indicators, and Radiofrequency identification (RFID) systems, have been introduced to market food, to improve storage conditions and safe, and reduce waste fresh meat products. However, each method has advantages and disadvantages, which affects the system performance.
