A delightful coffee or tea shop must have its unique products, which may include exquisite connotation and eye-catching packaging. PK Sleeve cannot change the ingredients of the products, but it can make the product more attractive.PK Sleeve is an ordinary paper cup sleeve with value-added function of easy carrying. with PK Sleeve, you have the options to use it as an ordinary cup sleeve or you can carry it by transforming into a carrying device. PK Sleeve is reliable, convenient, elegant and environmental friendly. When someone need to lift the cup, He can simply tear the two straps and buckle them up to form a handle. It allows carrying  2 to 3 cups of hot beverage with one hand. Hence, paper trays, paper bags or plastic bags will no longer needed. It is cost-saving and reducing the wastes. How about the price?  The price is not much different from the traditional cup sleeves, after all, it is made of papers!Various selections  of public versions or customized printing available.

Manufacturing Process of PK Sleeve

Manufacturing process of PK Sleeves are similar to those of traditional paper cup sleeves, which including die making, printing, flute laminating, die cutting and gluing. But since the PK Sleeve involves strength issue, therefore the material testing and the strength tests of final products are included. Due to the existence of extra straps die line, the accuracy of every single process would need a higher standard.


1. Material testing

Material testing includes : Grammage measurement, Water content, tension strength, tearing strength of the papers to be used. Papers will include the face liner, base liner and the flute layer. The strengths in the machine direction and cross direction will be tested separately. The testing methods are in accordance with the specifications of ASTM.


Material testing is important since the papers may include many kinds with certain range of grammage such as kraft papers, white kraft papers, clay coated papers, etc. Since the papers are produced form Paper and Pulp Factories worldwide and same type of paper with the same grammage might perform differently in the aspect of strength. We tested the tension and tear strength to make sure that the final products will meet the standard before the mass production started.

2. Die-Cut Making

A dieboard would consist of numbers of die module based on the size of the papers used. We will normally arrange as many as modules to lower down the cost. Unlike PK Sleeve, die-cut for traditional cup sleeve is relatively simple as picture shown below. As one can see, the dieboard is filled with ejection rubbers for PK sleeve. This is arising another problem. The cutting pressure would need to increase greatly in order to cut through the corrugated cardboard but when we do so the corrugated cardboard would be pressed too thin and the structure of flute medium would lose its major function - heat insulation. Therefore the control of the cutting pressure and the selection of the ejection rubbers are very important.


3. Printing

PK Sleeves provide both sides for printing that can be a good advertising tool unlike traditional cup sleeves, in which one side is for gluing joint and normally left blank or for less important information.


4. Flute Laminating

The corrugated medium is often 0.026 pounds per square foot (0.13 kg/m2) basis weight in the US; in the UK,
1c1ec9b34fa5a43f4b38098fb0d9dc47.JPGa 90 grams per square meter (0.018 lb/sq ft) fluting paper is common. At the single-facer, it is heated, moistened, and formed into a fluted pattern on geared wheels. This is joined to a flat linerboard with a starch based adhesive to form single face board. We then joined a second flat linerboard adhered on the top of the first linerboard to form single wall corrugated board (3 layers totally), by a laminator. The first Linerboard is recycled paper and the second linerboard (face liner) may be kraft papers, white kraft papers or other preprinted papers.

Common flute sizes are "A", "B", "C", "E" and "F" . Traditional cup sleeves normally use “E” flute. And this is also adopted for making PK Sleeves.


5. Die-cutting

Die-cutting for PK Sleeve involves a high level of attention to detail and meticulous still this is not easy to master. Die-cutting technicians will need to try several cuts and adjust the pressure for each module by adhesive tape.

PK Sleeve is sensitive to the thickness of the corrugated cardboard. If the pressure is too high it will press the cardboard too much and lower down the strength of the sleeves. Besides, a very thin cardboard cannot provide a good thermal insulation and lose the most important function of cup sleeves. On the other hand, if the pressure is too low it will not cut thought the cardboard and cause lots of problems for later folding and gluing process or even cause difficulties to our users while tearing off the straps. Therefore, we arranged different types of ejection rubbers to control the thickness of the products.




6. Folding and Gluing


This is the final stage of PK Sleeves making. The standard Gluing machine would encounter difficulties if there is no adjustment made. The machine is custom made for producing PK Sleeves only. With this machine, the folding and gluing process can be accuate and fast.


To further illustrate how the gluing machine folds and glues PK Sleeves. We like to share a short film below. This is a test-run of gluing machine. The maximum speed of production can be up to 34,000 pieces per hour.

One-stop manufacturing in Taiwan

we are one-stop manufacturer for PK Sleeve production. This would allow the impementing of quality control and lower down the cost.
