Application of Sealed Bottle Caps in Packaging Field (I)

CROWN can provide customers with "high-level concept" packaging design solutions because all the company's departments are working together. Whether it's beverages, foods, vacuum packaging, metal or plastic closures, CROWN can always provide companies with many choices to win the market.

In order to reduce package damage and shipping weight, and to meet the safety needs of consumers, many large retailers today require beverage and food manufacturers to use plastic packaging. In all aspects, while changing packaging materials, maintaining brand integrity and ensuring product quality is a major challenge. Because, a type of glass packaging that has long been accepted by the market and has a high degree of recognition, which consumers understand and trust to change into a plastic package, may cause a brand crisis in the consumer market. In addition, many products that require high-temperature processing, such as sterilizers and hot-fill packaging, face technical difficulties in this transition trend.

A composite seal cap, a two-piece cap that includes a central metal plate and a plastic outer ring, can help the brand smoothly transition from glass packaging to plastic packaging. Compared with ordinary sealing caps, composite sealing caps have more important practical value and stronger brand appeal. The composite seal cover can bring a brand-new image to the brand through the reasonable combination of materials.

Maintain a beautiful appearance

When we talk about packaging, we often have to consider the cost factor. Many prestigious brands don’t really care about price competition, but rather make a big issue on brand loyalty and brand familiarity. Whether orange juice or pickled products, manufacturers often use packaging as the first step in brand differentiation. Most metal sealing caps are not suitable for use in plastic cans and plastic bottles, but sealing lids made of mixed or composite materials can be used in plastic containers. The composite seal cap on the plastic container not only retains the traditional package appearance but also adds thread for rotation. Another reason for the popularity of composite sealing caps is that they are technically very safe and even if they are subjected to instant shocks, consumers do not have to worry about package rupture.

Brand display space

Most brands that use glass packaging with metal closures have realized the importance of marking the brand on the closure. The seal caps are used day after day in product packaging and become a link between consumers and brands. A well-designed composite package not only allows consumers who are familiar with the brand image to maintain loyalty; in addition, the metal that is beautifully decorated can also reflect a high-quality external and internal beauty associated with the brand.

For many products, converting packaging into plastic cans means that the pasteurization process must be met during processing. But before, the plastic sealing cap can not withstand the high temperature environment during the sterilization process, and the composite sealing cap can adapt to any requirement of high temperature pasteurization. This is to convert the glass packaging into plastic packaging, or convert the plastic packaging into glass packaging. A major step forward.
For example, CROWN has designed an "IDEALTM" seal cap for Libby to hold jam products and advanced fruits that need to be pasteurized. CROWN also designed a smaller-diameter, distillable composite seal cap for Ross Products to preserve the company’s best-selling nutritional drink “Ensure”. The highlight of the current "Ensure" promotion is the sealing lid of the product, which can be re-covered after opening. To date, CROWN has successfully implemented this conversion for packaging seals designed for ketchup, applesauce, jams, jellies, orange juices, and baby formulas.

Practicality and safety

Consumers always associate metal materials with first-rate quality, but at the same time they are particularly concerned with the convenience of product packaging. A composite seal cover made of a combination of a metal top cover and a plastic pull ring provides an optimal solution. The plastic pull ring is easy to open and also has an important safety feature.

The composite cover with safety protection is divided into two layers. The first layer is attached to a metal disc to protect the airtightness of the container. Only by rotating the outer plastic ring and lifting the metal disc will the seal break. Before the gasket ruptures, the anti-theft press-down structure in the plastic ring falls off, providing consumers with a second layer of protection. Thanks to this anti-theft structure, the production process of using a foil layer inside the cap is eliminated, thereby reducing the production cost and improving the operating efficiency of the entire production line. The choice of the container and the shape of the container can influence the amount of torque set to open the seal ring, which enables the brand owner and packager to balance both safety and convenience.

When consumers open a product package that uses this composite seal cap, they will still hear familiar “squeaky” sounds, but they no longer have to worry about safety issues. This "click" sound is to further improve the anti-theft performance of the closure, but also an emotional bond between the product and the consumer. Because when consumers hear this "squeaky" sound, it seems to tell them: Hey! This product is more fresh!
