The company, Method, overcoming all sorts of difficulties in design and manufacture , firstly developed one kind of new packaging, about 53 ounce, by using 100% recycled PET bottle. With strong shelf appeal and excellent environmental protection function, Method adopt this new packaging to the new laundry detergent products.

Method expanded the company's laundry care product line, and launched one series of four-time concentrated laundry detergent products . Those new products use 53-ounce, 100% recycled PET resin bottle after consumption (Amherst branch company offer).This new packaging serving as a smooth and transparent custom container, with strong shelf appeal, is the first application in the industry of 100% PCRPET resin laundry detergent bottles.

Joe Hunter, the director of Method packaging company, said, " with colorful hand sanitizer and multi-effect clean formula product adopting transparent PET bottle packaging, Method has opened up a new road in the laundry detergent market. The application of PET bottle is not only attractive in laundry detergent market, but also in our other products such as hand sanitizer and multi-effect resonated detergent products. It is a great achievement in the market area which only limited to opaque HDPE containers previously."
 
Now this new 4x concentrated laundry detergent bring a supplement into Method who is only limited to 10-ounce, 20-ounce and 30-ounce HDPE container to pack 8x concentrated laundry detergent products.
 
According Matt Lewis, the senior development engineer in the hard plastic department of Amcor, so far, PET relying on strong compatibility and color stability has been successfully adopted in the laundry detergent market. Before this, Amcor has done compatibility test for the Method’s liquid formula, to ensure the stability of the products packaging on store shelves. Amcor firstly did the tesrt for the preform, and then made a further stability test. The results show that everything is fine.
 
The design team of Amcor, working closely with Method’s industrial design team, launched a unique packaging ----sessile stretch blowing bottle packaging, which shows a style of Method’s own. The mold design has certain challenges in the crossing angle dividing line and high function according with human body engineering in the neck of the handle design. However, by setting a variable radius separation line, this problem can be solved.

Because of using polypropylene dumping mouth and adopting the structure of the over cap, the design of the neck is also seemed to be challenging. The dumping mouth needs to fix bottles’ position to the front of the bottle mouth. Once the position is fixed, it is not able to rotate through the the dumping cup. It is quite complicated, because PP cap is specially designed for high density polyethylene bottle.The neck of the handle design also experienced a series of design experiments to find the best option. In addition, in order to fill the bottles easily, the height of the bottle shoulder also did some adjustment.

Hunter said: "adopting 100% PCR PET 53-ounce containers has greatly contributed to the Method to insist on company's sustainable development strategy. One of our major business starting point is to reduce the impacts of our products on the environment. Amcor ASSET life cycle assessment analysis shows that using 100% PCR resin, packaging life cycle energy consumption is decreased by 78%, and its carbon dioxide is decreased by 35%, compared with the original PET material.’’
