With the improvement of packaging safety requirements, the types of packaging materials are also increasingly diversified. Packaging materials must have high barrier properties, oxygen barrier properties, moisture barrier properties, air permeability, high tensile strength, tear resistance, impact strength, excellent chemical stability, high temperature resistance, and content The requirements of high temperature sterilization and cryogenic storage. In order to meet these requirements, it is necessary to improve the production technology. The following is a brief introduction to foreign technologies.
BOPP aimed at PET juice packaging, compared with the traditional sterile paper packaging, three metal cans, glass bottles, BOPP has a lower cost, good heat resistance, transparent material, light weight, easy to damage, good environmental protection Etc. The improvement of the heat resistance of BOPP is through the PP stretching process, the bottle mouth does not require special equipment to handle, so that the oxygen barrier performance is greatly improved; the storage period is longer, easy to recycle, the product cost is more than 20% cheaper than the PET bottle, has been obtained More and more widely used.
Taking into account BOPP's cost-effectiveness, Tampico, a world-renowned juice beverage manufacturer in Chicago, decided to use BOPP containers as packaging for children's fruit juice products Tampikids. The company claims that the PP produced by the manufacturer Milliken occupies a huge advantage and can compete with PET in juice packaging. Our goal is to use innovative products in packaging technology, that is, to use BOPP products to ensure that we enter the market with the best attitude and quickly occupy a place to embark on a successful journey of product marketing, Tampico Technical Product and Packaging Development Department Manager Sergio Romeiro said that when our business expands to Europe and Asia, the demand for products on packaging will be even greater, and the technical support behind packaging containers will become even more important. â€
Tampico requires that production costs be reduced to a minimum when the juice content is increased without the use of preservatives. During the pilot test, Mi11iken collaborated with PP makers Braskem (São Paulo, Brazil) and Packpet, a Brazilian company that uses the SBO 2+ series equipment to generate 5 to 20 liters of water using the ISBM (injection biaxially stretched forming) technology. PET bottle.
“With recent efforts, we applied biaxial stretching technology to PP and developed a 250-ml hot-filled bottle that was designed and integrated with Tampico's design. Marita Janowitzer, Milliken Latin America Sales Manager, said, “Under hot-filled conditions, bottles do not Deformation also shortens the operating cycle and increases hardness. Although no preservatives are used in the juice, the contents remain fresh in warmer environments. Janowitzer confirmed that the production efficiency of PP bottles produced with MiHad 3988 can be increased by 30%, which is equivalent to PET production. In addition to the low cost of the resin, the PP material in the core is superior to the PET material for a specific container, and the replication molding is very easy. The hot filling temperature can reach 98°C, which makes the beverage plant's hot filling possible. The process becomes easy. The appearance of the bottle is very similar to that of a PET bottle. It is transparent and colorless, and it is favored because it can reveal the true color of the beverage itself.
The competition between PET bottles and BOPP bottles will begin in the market of hot-filled beverages, especially tea beverages. Because packaging costs are too large in the cost of beverages, even companies that have already used PET hot-fill bottles may switch to BOPP bottles, and some newly-invested beverage companies will likely use BOPP bottles directly. In addition, BOPP bottles are more excellent in terms of safety, hygienic properties, and taste retention of contents, and they are also more environmentally friendly, so they are entering the pharmaceutical packaging field.
The new material should not be overlooked. EL0 is very effective in replacing traditionally used encapsulation materials, such as mineral water bottle caps, because this material has almost no odor and it can be used in oxidizing environments such as high temperature, ultraviolet irradiation, oxygen, and ozone. Provide good stability in the environment and some warehouses with poor storage conditions to ensure that the contents do not deteriorate. VO provides excellent lubricity properties when polyolefin films are formed and can replace tallow. It also speeds film formation, especially for linear low-density polyethylene (LLDPE) and LLDPE mixed materials with low-density PE. The new titanium dioxide is eye-catching. Tiona 125, a new type of titanium dioxide pigment, is used to meet the demand for plastic masterbatch production. It is easier to handle at higher temperatures, is less volatile and easily disperses. This material has the best particle size ratio and has better optical effects than previous products due to the use of a surface treatment technology (patented) and continuous improvement in production. The surface treatment technology reduces the filter blocking and compensates for the film's inadequacies.
The active packaging material WingstayL Antioxidant helps retain fresh color and increases the life of ABS. The combination of ABS and this multifunctional antioxidant has improved the performance of heat aging and greatly increased stability. Compared with monophenols and bisphenol antioxidants with similar functions, Wingstay L antioxidants have lower volatility and higher activity, and can be used to filter out detergents and prevent them from getting dirty. It is worth mentioning that it has formal food contact permission. This powder has an average particle size of 10 μm and an ash content of less than 10%.
The magic charm of the small application Miraval KU28, a bright and beautiful magic white pigment, can combine a colorful high-light area with silvery white through reflection to show colorful light. It is attached to less than 1 m thick boric acid boards. The smooth surface material minimizes scattering of light and maximizes pigment transparency. It can be applied to a variety of resins, including opaque or translucent polymers. Thermoplastic. It is extremely stable and browning does not occur even if phenol is added. Merck Europe and North America EMD Chemicals Co., Ltd. are sold.
The new strength of flame retardant display packaging, Exolit OP, is a plastic product that is comparable to the flame-retardant properties of reinforced glass fibers. It strictly complies with the fire protection standards and can achieve ideal results by adding very low doses. These non-halogenated flame retardants, based on metal phosphates, have a good value for money. The latest addition to Exolit OP is 930 9355111230-grade. The main development direction is to add adhesive series products and sealing materials based on hydroxypropyl acrylate epoxy resin or polyurethane. These non-toxic products are insoluble in water because of their low density and are suitable for the transport of light materials.
High-speed processing saves costs. PP filled with 60% calcium carbonate (Omyalene 102M and 112M calcium carbonate) can replace the polystyrene used for thermoforming (PS). PP can be faster on existing PS process equipment with the same line speed. It is processed. Omyalene 102 M and 112 M calcium carbonate are easier to disperse in standard polyolefins (POFs), increasing the material yield and cooling the product faster on the chill roll. The semi-finished product has the same amount of expansion and contraction as the thermoformed PS. It is mixed with PP to produce isotropic machinery and speed up the molding process to make the cutting accurate.
Halogen-free flame-retardant materials Flame-retardant materials are suitable for polyurethane (PUR) foams and thermosetting materials with very high hardness. Halogen-free material DMPP is a low-viscosity product with a phosphorus content of more than 20%. It can replace all or part of the halogenated material in the foam. Halogen-free phosphate esters, like flame retardants in many resins, dissolve together with the resin. For example, they can be blended with vinyl resins. They can be used in conveyor belts or cables, which not only provide flame retardance but also increase plasticity.
Nano-materials nano-composite packaging materials will gradually become industrialized with the rapid development of nano-technology. As their wear resistance, hardness, strength barrier, and plasticity are significantly enhanced and improved, they can be used in addition to food packaging. Special packaging, such as anti-static and anti-electromagnetic dangerous goods packaging, is expected to promote a tremendous transformation of traditional plastic packaging materials.
Nickel inhibitors are used in agricultural films. A nickel-based UV dust-resistant stable material is available. It is granular and is a mixture of a nickel inhibitor and a UV absorber that enables polyethylene (PE) The melting point is lowered and the problem of easy dispersion of polyethylene can be solved. Although PE agricultural films were exposed to poor climatic conditions and insecticide environment, with the help of this dustless mixture, IJLowilite Q21, it was also protected from seasonal changes. Since nickel powder can cause allergic reactions, post-treatment of nickel has been a problem.
Biodegradable plastics Biodegradable plastics not only have the functions and characteristics of traditional plastics, but also can be split and reduced in the natural environment through the action of microorganisms in the soil and water, or through the action of ultraviolet rays in the sunlight, and finally reintroduced in a non-toxic form. Human ecological environment. China's biodegradable plastics are developing rapidly, but their market share is still low.
With the development of science and the attention to environmental protection, plastic packaging closely related to people's lives is also attracting attention. More and more materials are dazzling, but the theme is only one: environmental protection, energy saving, green, and healthy.
