Today, the importance consumers attach to the environmental impact of packaging cannot be ignored. Market research also tells us that many companies in Europe and the United Kingdom have raised their environmental awareness. They are constantly looking for "greener" production methods and ways to eliminate unnecessary waste. Many packaging companies are increasingly favoring thinner tissue paper, and thinner or even linerless paper labels because they help reduce shipping volume and reduce the carbon footprint. Because the technology of backingless paper labels can meet the dual requirements of enterprises for economy and environmental protection, it is not surprising that it is welcomed. Now we can see that the market demand for backing paper labels is growing.
Advantages of linerless labels
The three parts of self-adhesive materials include surface substrate + adhesive + backing paper. After the sticker is attached to the package, the mission of the base paper is completed. In most cases, the practice is to discard it, which brings a lot of waste. In the packaging industry, retailers and regulators demand reduced packaging waste. When end-user manufacturers face this unprecedented pressure, the advent of linerless labels has brought new hope to the industry.
Backingless label, as the name suggests, is a self-adhesive label without backing paper. The bottomless paper label does have obvious advantages, it can reduce waste. In addition, the bottomless paper label can also save costs in storage, transportation and pasting. Because there is no backing paper, paper rolls of the same size can hold more labels (more than 50% more than ordinary paper rolls), which can reduce the cost of a single label and reduce the frequency of paper changes. More labels per roll means reduced storage and transportation weight, reduced label stock, significantly reduced waste on printing presses and packaging lines, reduced energy consumption of mobile waste, environmental protection, and more sanitation.
Application of linerless label
The elimination of backing paper can save a lot of production costs. To make bottomless adhesive, there are several problems to be solved: the glue is not sticky before use, and it becomes pressure-sensitive adhesive during use by heating or UV irradiation; the change of the die-cutting method of the bottomless paper label needs to design new Die-cutting equipment adapts to linerless paper labels; similarly, automatic labeling machines for linerless paper labels also need to be redesigned.
With the gradual expansion of the linerless paper label market, labeling equipment suppliers have also introduced equipment to the market that can produce linerless labels.
British Etiquette label company recently launched a linerless labeling system. According to reports, their TT-PA EVO 150 can increase the number of labels per roll by 40%, thereby reducing the cost of waste treatment, storage, transportation and other related links and the consumption of paper. Atwell also stated that they are "very concerned about environmentally friendly linerless labeling technology" and launched a series of printing and labeling equipment for the market. These equipment can reduce the cost of labels by 30% and increase the number of labels in a roll by 60% .
The bottomless paper labeling equipment of Ravenwood Packaging Company in Bury St Edmunds can realize the labeling of bottomless paper labels, and can also achieve the flexibility of labeling in different forms and different positions such as top, side, C-shaped wrapping and full wrap Convert without replacing any parts. Paul Beamish, the company's general manager, said he saw the market's demand for linerless labels growing on a large scale. "For the past four years, we have been providing backing paper label solutions, and have installed more than 500 labeling machines in the United Kingdom and Ireland. The benefits of backing paper labeling machines include faster production line speeds and faster Production conversion, cost savings and environmental protection. "
The bottomless paper labeling system developed by Session is suitable for top labeling and lateral labeling. The label on the label roll is perforated and driven by a pair of conveyors. When the perforation point reaches the interface between the two conveyors, the first conveyor stops and the second device accelerates to remove the label from the punch After tearing it off, the separated label is transferred to the end of the conveyor, waiting for labeling.
Xact Lawtons Group branch and HM labeling company also jointly developed a linerless system, their target market is the United Kingdom. The Arla Foods company in Denmark installed the system for the first time. They installed a set of equipment for labeling cartons and pallets three years ago, which has saved a total of 30% of the cost of labeling. , Indirect cost savings due to faster speed of standard replacement and reduced maintenance costs.
Hatfield Quality Meats, based in North America, also applied bottomless paper label packaging for its 48-ounce and 16-ounce sausages in the spring of 2010. They use bottomless paper labels to replace the traditional top and bottom labeling methods in order to reduce inventory risks and reduce packaging waste, while also improving production efficiency. The environmental performance of the linerless label is one of the main reasons the company likes. "We hope to find a more environmentally friendly form of packaging to support our sustainable development strategy," said Michael Bracrella, vice president of Hatfield Quality Meats.
The bottleneck of linerless labels
There is no doubt that the bottomless paper label is indeed very attractive to businesses, especially those with economical minds. However, the linerless paper label technology also has its own shortcomings. Richard Scott, UK marketing and product manager for labeling equipment manufacturer Sato, said: "Over the years, most of our machines have been able to produce linerless production, and market demand for this is also increasing year by year. This demand is stable , But not very large, because users need to change their existing systems, and some users are reluctant to do so. Because the bottomless paper label system is more expensive than the traditional labeling system, the customer's investment is greater.
In addition to cost factors, the limited shape and variety of labels that can be produced or operated on linerless label systems are obstacles to adopting this new technology. Peters Haw of Sessions said: "The shape of the label is limited, and the connection between the labels must be kept at a sufficient width to provide sufficient strength. For example, a diamond-shaped label will become very difficult because The shape of the label roll does not have sufficient strength. So the most common shapes of labels in this process are oval, rectangular and square. "
In addition, the removal of the self-adhesive backing paper makes the self-adhesive label form like tape, which inevitably causes the pressure-sensitive adhesive to contact the label surface. In order to protect the surface and prevent the bottomless paper labels from sticking to each other, the manufacturer adopted the method of coating the surface of the label with silicone oil to release, which affected its impression of "green" in people's hearts.
Introduction to woven bag
Woven bag, also known as snakeskin bag, is a kind of plastic packaging, made of warp and weft interwoven.Because of its use, color, weight, length, width and other parameters, woven bags are divided into a number of different.Its application has been extended to agricultural and industrial product packaging, food packaging, geotechnical engineering, tourism transportation, daily necessities, flood resistance materials, special woven bags and other fields, greatly facilitating people's life.HDPE flat silk fabric feel soft, lubrication, not dense. In the PP flat silk added calcium masterbatch, feel wide,PP less HDP,}, movement, the purchase of the proposal to see the sample before purchase, only in this way to buy a reliable bag!
