Advantages of PET Jam Jars in Labeling Cans
In July 2009, LiDestri Foods made major changes to its product bottles. They introduced a new, sustainable single-layer PET bottle from Constar International. This kind of customized brand container has greatly enhanced the company's production efficiency while making the product look more friendly and friendly to the environment.
The Francesco Rinaldi hot-filled wide-mouth bottle made by Constar uses a unique recyclable PET material, combined with a correction technique, made by a two-step injection/stretch blow molding process.
As one of the largest producers and contractors of pasta sauces, sauces, and miscellaneous sauces, LiDestri has previously used Francesco Rinaldi sauce with different sizes and materials including glass bottles and HDPE. The new PET cans they have recently adopted have a rigid feel and are unique in appearance. LiDestri has four USDA-certified factories that produce more than 2 million bottles of sauce per day.
In addition to sauces, the company also produces various beverages, spirits, oil, vinegar, cooking wine, syrups and jams through hot filling, cold filling and distillation techniques. This PET bottle looks very trendy and has a pattern of raised tomatoes on the shoulders of PET bottles. Each plump tomato has a “dimple†on the top and a dotted line of rhizomes. Lifelike, as if they were freshly picked. Supplemented by the delicious red tomato sauce in the bottle, even more real and moving. With 45 ounces of Francesco Rinaldi products with such a good appearance, consumers who are looking for pasta sauce in the supermarket are almost irresistible. Compared to the previously used PET bottles with side grips, the new bottles are "thin" 8 grams and are more consistent with sustainable development. In addition, the iconic detailed instructions on the new bottle document LiDestri Foods' 50 year history of accumulation in the food industry, making the new product more appealing. To achieve lightweighting requirements, Constar used CONSTructTM advanced predictive engineering software to design, model, and produce PET bottle packages, providing LiDestri with the packaging performance needed with less material cost (11% material savings).
With Constar's technology, containers can be made lighter in weight, whether they are glass to plastic bottles or plastic to plastic. Before the packaging was put into production, Constar built a very sophisticated model to predict possible performance deficiencies, thereby avoiding poor packaging design.
In order to achieve the necessary strength of the bottle, Constar used the company's patented design process vertical compensation technology (VCT) to adapt to the initial temperature and cooling process of hot filling without the need for paneling or folding. LiDestri said that this new PET bottle is comparable in hardness to glass bottles, and it also brings a premium brand image to the product.
The application of this technology allows the vacuum board to quietly withdraw. In comparison, it provided a new 45-ounce pasta sauce package that many LiDestri's original side grip bottles had never had before.
“Because the bottle uses a single-layer structure, it also avoids the risk of delamination,†said Suzanne Cohen, senior marketing manager at Constar. “Layering creates potential aesthetic and functional deficiencies.â€
From the bottle type aspect, although the previously used side grip bottles provide consumers with some convenience, but because of its asymmetry to labeling caused great difficulty, so that the unique bottle type stickers Labels became the final choice for helplessness. Based on this, LiDestri is very much looking forward to using a round bottle, which can adapt to the winding label, and it can also improve the efficiency of the production line, and it can also eliminate the need to straighten the bottle to ensure that the labeling site is accurate. Mark McAndrew, Project Manager at LiDestri Foods, said: "As we expected, the new bottle is made of PET, and its round shape has helped us increase productivity. We like the winding label because it is packaged On the expansion of advertising space, which is very meaningful for product promotion."
Constar Marketing Director Alex Fioravanti explained further: “The VCT technology makes labeling easier, so you don’t need to re-adjust the direction of the bottle. The easy-to-hold feature does not disappear, but moves through the shoulders of the bottle. To the bottle mouth.†McAndrew said that because the previous PET bottles needed to be labelled before and after, it was difficult to control the alignment of the two labels, not only slowing the labeling speed, but also caused a lot of waste. However, we still maintain the Pace orienter on the sauce packaging line in order to run oriented packaging containers on other sizes of production lines.
The improved bottle has a horizontal rib lap in a circle. It uses a roller provided by Fort Dearborn and a two-piece sealing cap provided by Crown. McAndrew pointed out that another benefit of this bottle is that the company only needs to purchase a little conversion parts and a different labeling machine (provided by Krones) to run new bottles on existing equipment without additional equipment adjustments. .
In addition, the new bottle's maximum load intensity has almost doubled, McAndrew said: "After the maximum load capacity has been strengthened, we can stack the bottles higher and reduce product damage during storage or shipping."
Independent testing by the Rochester Institute of Technology has shown that this VCT-enabled bottle can be stacked to five pallet load heights in the finished product.
Symmetry and sustainability coexist
The bottle after filling is sealed and placed in a corrugated box on a tray packing machine/shrinkage combination channel in groups of eight, and then bundled with a shrink film.
LiDestri chairman and CEO Giovanni (John) LiDestri said: “The original PET bottle was not working well because of the problem of labeling, and our production line speed was reduced, which led to a drop in production. Our production line is very busy. Accelerating speed is a must, VTC design is very symmetrical, labeling is clean and does not make mistakes, rarely leads to production line downtime, but also reduces the waste caused by improper labeling.The new packaging gives us a more stable and predictable stickers. The bidding process has a positive effect on the improvement of overall production efficiency."
The process of filling the sauce is carried out on a rotating Elmar system. After filling, the bottle is capped on the rotating equipment provided by Fowler Products, followed by the labeling on the Krones equipment. Afterwards, the bottles will be placed in groups of 8 in a corrugated box on the Krones tray packer/shrinking channel and packaged in a transparent shrink film.
Smooth operation
Nowadays, the new bottles are working orderly on the production line, and LiDestri also enjoys the benefits of this eye-catching and environmentally friendly packaging for retailers and consumers. Now that it has been accepted by roadside recycling programs, this PET bottle can be recycled again into new packaging, or items like sleeping bags, clothes, or even car tires.
