The problems of packaging closuresare diverse, like convenience, sustainability and connectivity.

First of all, it may be hard for consumers to open a tube or take a long time to get all products from a tube. When individuals age, it is a difficult task for them to extrude a tube to get the last bit of a product since they do not have much strength. Some people even cut off the packaging to use the product. To solve this problem, several systems cooperate with each other to cut down 80 percent of waste while orthodox tubes just dispense about 75-80 percent of products. This design does not need to use a dispensing pump but it can achieve its goal, the evacuation rate of 100 percent. This design can help customers get the product accurately and dispense efficiently even though the product is thick. It can be used in any positions.

Another challenge for the elderly is opening tubes. They are not strong enough to open a bottle. Hence, a company makes a kind of closure making it easier to be opened and reducing the time to deal with the capping line which looks like a flower. This closure is advantageous for all ages. For example, when parents want to open canned food, like fish, infant formula or milk powder, a peelable end can save their time and prevent oil from splashing.

Additionally, the packaging industry pays much attention to sustainable development so manufacturers have to look for solutions to solve the problem. Someone said they can decrease the weight of products to use less material. For instance, a technique which is 16 percent lighter has the same performance as a dry food can. It is more eco-friendly as it saves 32 percent of energy and all the metal packaging can be recycled many times.

Customers also have the awareness to use recyclable materials instead of plastic, which helps corporations to strengthen distinction. A typical example is that a brand uses sugar cane to replace plastic closures and caps. Sugar cane can absorb carbon dioxide and produce oxygen so it is environmentally-friendly. Moreover, some companies manufacture post-consumer resin and sustainable resin alternatives but the supply and cost are great challenges. Talking of recycling, cleaner products are easier to be recycled so they should be cleaned. Consumers focus much on health so natural products are of great demand. Companies can reduce preservatives through altering packaging. For example, airless squeezable tubes can prevent oxidation and color change so there is no need for preservatives.

Finally, packaging is vital for brand protection as progressive packaging can avoid counterfeiting to some extent. For instance, QR code and secure fingerprint are combined to be used on closures. People can distinguish products according to the feature without any other equipment like scanners.

The closure market can help suppliers get the data of customers to improve their participation. Therefore, the pharmaceutical market is able to acquire feedback so that it can give some suggestions to patients, such as reminding they of eating medicine, and finally, improve their health. What is more, there is also innovation in this area. For instance, a brand wants to demonstrate a high-end image so a 100 percent metallic material wrapped around the skirt of a closure is demanded, which is unprecedented.

All in all, many companies take actions to deal with the problems of packagingclosures.
