Innovative design of packaging containers for dairy products (Part 1)
as far as packaging products are concerned, what is contained in containers is of course important, but packaging containers are equally important. Packaging, which has been closely related to product development and marketing, has more and more styles for today's diversified dairy products, especially plastic bottles and cartons that have rarely changed in appearance and material for many years. At present, their sizes are changing, Shapes and colors are varied
when the appearance of the goods in the dairy sales counter fades to unknown, dairy practitioners can just take advantage of the current business opportunities and existing technologies to select suitable packaging containers from many different packaging styles and materials to highlight the products. A single serving of liquid milk has changed the way milk is bottled, and it is packaged in PET bottles. Dairy producers are more original in distinguishing their fine mouthed bottle products with unconventional shapes, more unique labels, bright colors and convenient bottle caps, and even using light blocking materials. In terms of cartons, the standard traditional mountaintop cartons often strengthen their containers with different characteristics, from the rotating top cover to the impressive cardboard printing pattern
dairy products themselves should have changes in performance, such as the demand for extended shelf life, which has a great impact on packaging design, packaging performance and the barrier of packaging materials. The field of packaging may not be limited to these, but these types of packaging technologies are certainly taking off. John hoeper, marketing manager of Pechiney plasticpackaging Department of Alcan in Chicago, said, "the new development of dairy industry and the continuous expansion of dairy beverage market are the driving force of our development. They really drive the growth of packaging market."
the increasingly extensive dairy market has prompted packaging suppliers to create many new customized packaging bottles and boxes in innovative ways, using emerging technologies and materials. Murray Bain, vice president of marketing of stanpac Inc. (snithville Ontario), a supplier of glass bottle caps and glass bottle capping machines, said, "because the dairy industry now produces dozens of products, we need to prepare more inventory."
in order to catch up with the market demand and make good use of the latest materials and equipment, some packaging container suppliers are already upgrading. Burd & Fletcher, a supplier of cartons for food John mycklemoe, vice president of sales of indepnence, Mo., said, "our customers want high-performance cartons and containers that look wonderful, have high filling efficiency and are suitable for transportation and marketing. To achieve this goal, we redesigned one of the equipment and introduced the latest printing and carton manufacturing technology to help us build a perfect supplier image of customer first."
I. bold plastic bottles
at present, plastic bottles used to hold dairy products such as liquid milk, yogurt and energy drinks with milk as the main nutrition are really all inclusive. In terms of liquid milk, traditional high-density pet is still the most commonly used material for plastic bottles with handles and general plastic bottles, because it is moderately priced and quite reliable. In addition, under the stimulation of single serving seasoned milk and large bottled milk, high-performance PET bottles are popular because of its light weight, many changes, and can be cast into strange shapes and styles. PET bottles can also be different brands and models with different product functions. Shrink labels are placed on the bottle to increase the color and eye-catching patterns of the container and attract consumers to buy
a new field in plastic bottle packaging technology is the development of multi-layer high barrier materials for products that are easy to oxidize. Pechiney has developed a new type of high-temperature sterilization plastic bottle called gamma, which is used for milk based nutritional drinks. Hoeper said, "we follow the pulse of the market and show our strength. At present, the market has expanded to the field of normal temperature preservation, that is, the field we want to intervene in." According to Tim bubble, director of research and development of Pechiney, gamma plastic bottles are made of multi-layer materials. He said: "we are dealing with products that are sensitive to oxygen, so we use a standard 6-layer structure with an oxygen barrier layer. We have done a lot of research on PP material to prove that it can withstand the temperature of sterilization kettle." The sterilized bottle is sealed with a two-piece bottle cap, which is composed of a disc-shaped metal surrounded by a plastic layer, so that the product can be sealed and protected without using an inner lining
hoeper said that this new plastic bottle was successfully developed with the joint investment of three major dairy producers, He said, "we have worked closely together for two years to develop plastic bottles suitable for their processing. We have a deep understanding of the packaging needs of dairy drinks. He further said that such packaging products will soon be widely available in the U.S. market.
for these single serving plastic bottles with a packaging capacity of 8 to 16 ounces, a very promising application field is vending machines and school catering services. Bubb said: "At present, the situation of the market is that schools should exclude carbonated beverages, and milk based products will replace them. Some of these dairy products are canned, but most of them are economical and low-carbon. Qinghai province's waste asphalt pavement materials have significant benefits from geothermal regeneration technology. The plastic bottles that can be opened and resealed are the containers we can supply." With similar ideas, Graham Packaging Corp (York Pa.) recently launched a new kind of sterilization resistant plastic container. The plastic bottle originally used for nutritional drinks is made of multi-layer PP material with a temperature resistance of more than 250 ℃, Markleiden, Graham's vice president of global marketing, said, "this technology is finally available, and we can also use it to develop this kind of sterilized plastic bottle. Until now, it is still difficult." he further stated that the probability statistical method has been used to deal with fatigue experimental data since the 1940s. The products of the sealing machine can be one-piece bottle caps or aluminum foil caps. This new plastic bottle developed for nutritional drinks is a square container, It has the function of saving muscle strength, which is convenient for the elderly
leiden said that Graham also supplies this kind of sterilized bottle to other nutritional drinks that can be preserved at room temperature, and this kind of PP bottle is also supplied to drinks that are mainly milk and mixed with various fruit juices, such as comfortable and energetic drinks. The key factor for Graham to enter the dairy beverage market other than liquid milk is whether it can form a close relationship with manufacturers interested in the development of special products. He said, "for example, we only supply yogurt beverage bottles sold at room temperature. Our containers are 100% customized, which limits their use in the field. All containers are made for the needs of customers."
although multi-layer plastic bottles for extended shelf life and non-traditional dairy drinks can reflect the future trend of packaging technology, and although pet and HDPE bottles are the best choice for many liquid milk products in packaging containers, other dairy companies continue to use refillable glass bottles to establish their brand characteristics. They may have existed as early as the era of using carriages to transport milk, but they are not complacent. For example, stanpac has long supplied glass bottles to regional small dairy producers and national cooperatives, although the glass itself has not changed much. However, the company has made progress in its ability to print patterns and color performance on glass bottles. In recent years, stanpac has invested in the most modern printing equipment, using a direct printing method called ACI (Applied Ceramic labeling) to decorate glass bottles. Stanpac has also responded to the changing needs of the glass bottled milk distribution chainBain said, "we are studying a one-way recyclable glass container and hope to launch it at the end of the year, which is different from refillable glass bottles. At present, some grocery stores are not interested in any refillable containers, but specific dairy producers may have a good understanding with customers. If we put our products in recyclable glass containers, we will not damage the faith of dairy producers, so that they can have greater distribution." Bain said that in 2003, stanpac created a new bottle cap for a dairy manufacturer in Illinois, using a new one-piece anti modification bottle cap to replace the original compression tight crown cap. Over the past five years, we have designed molded anti modification bottle caps, which have replaced the old pressed aluminum foil caps. At present, most of these old bottle caps are no longer used. He added: this change is inevitable. In fact, the old bottle cap has existed since the 1900s, and it cannot be said that it is a short-lived bottle cap
