Small plastic cap, big business opportunity!
How strong is the waterproof ability of the cap for the tube?
The packaging industry the market is developing faster and faster, the cap is necessary for the packaging tube. Although it is a small plastic cap, its demands are huge in the packaging industry, like aluminum tubes, plastic tubes, and aluminum laminated tubes (ABL tubes).
With the changing consumer preferences and intermediaries’ demand, the plastic caps packaging design is also constantly pushing the new, a small plastic/metal cap contains a great business opportunity.
Packaging tube cap development speed has exceeded people’s imagination, in life, we can see everywhere the application of the covers, for example, shampoo, cosmetics, detergent, etc., can see the role played by the cap in our daily life. The covers have a very important protective role for the tubes, which protect the product inside from outside contamination and are waterproof.
From the simple plastic round caps in the past to the diversified spray pumps and caps now, this process of change is based on the overall needs of people, round bottle caps are not as strong as those tube caps for cosmetics leak-proof. The tube cover can prevent moisture from the outside from going directly into the bottle, and for cosmetic storage, the hose cap is better at preventing moisture from the outside and bacteria from entering the cosmetic inside. And with excellent gas barrier performance, it can effectively prevent the infiltration of oxygen and odor gases, and at the same time prevent the contents of the fragrance and active ingredients from leaking out.
Therefore, the waterproof capability of the tube cover is relatively strong, and it can directly improve the grade of the cosmetic packaging and the user’s experience.
Aluminum tube with a good lid match, aluminum tube value-added a lot
Cosmetic aluminum tubes, instant glue aluminum tubes, hair dye aluminum tubes, all-aluminum glue tubes…so many types of packaging aluminum tubes, do you know what they have in common? One thing in common is that they all need to be paired with appropriate and high-quality caps that are easy for consumers to open while also maintaining excellent quality when opened for use. But then again, how should aluminum tubes with caps match in order to add value to them?
First of all, one should have an understanding of the type of aluminum tube with a cap. At present, the more widely used covers are conventional caps (with/without spikes), stand-up caps, octagonal caps, common long nozzle caps, two-section long nozzle caps, safety covers, and on-sert caps, etc.
What decides which caps for your packaging tube?
So, when customizing and purchasing aluminum tubes, how should we decide on the aluminum tube matching caps?
When choosing the cover, the first consideration is the mouth and thread of the aluminum tube. The threads of aluminum tubes are M7, M9, M11, M13, M14, M15, and the most common ones are M7, M9 for small diameter tubes (Dia.13, .5mm, 16mm, 19mm, 22mm) such as medicine tubes, and M7, M9 for slightly larger tubes such as Dia.22mm, 25mm, 28mm, 30mm, 32mm. M11, 28mm, 30mm, 32mm are generally used, of course, some customers choose M15, while the larger Dia.35mm, 38mm, 40mm generally use M13, M14, M15 more, so with a larger cap is also more beautiful and practical.
Why are there so many different threads?
This is because for some products there are special requirements, the larger the threaded mouth, the larger the caliber, and the more capacity outflow. For example, medicine tubes are generally smaller in diameter, and the amount of one-time use is smaller, so a smaller thread can squeeze out a small amount of product without overdosing. For products such as hand creams, the M11 thread is the right size, no more, no less, and for some products that require a larger amount, such as hair dyes, the larger thread means that it takes less time to squeeze out the required amount of hair dye cream. As for the glue tube, for better use, a pointed nozzle is usually used.
How many kinds of caps are there in the market?
There are many kinds of lids in the market, there are hundreds of lids in the Chinese market, so what kinds of lids are there?
From the material, there are plastic caps, metal caps, wooden caps
Plastic caps are made from polyethylene, PP, HDPE. There are mushroom octagonal caps, round caps, screw caps, and flip-top caps.
And now there are also metal caps made from aluminum or zinc alloy, aluminum octagonal caps, alloy caps
For wooden cap, there is very very less in aluminum tube, but it is popular in plastic tube and laminated tube.
Conventional lids look similar in style, but they are different because of the different threads of different manufacturers. During the production of aluminum tubes, we need to make adjustments according to the number of threads to ensure that the aluminum tube filling will not leak.
How to choose the right cover in 2022?
One of the most important principles is that the tube and the cap should match so that the filler will not leak. Customers also choose the right cap according to their own requirements and brand image.
For pharmaceutical tubes, simplicity is the main concern and a common screw cap is good.
For skin care products with aluminum tubes, the choice of cap style will be more, using different caps with the whole tube and printing will look more different, and a little increase in the cost of packaging tube will not affect too much but may increase a lot of sales and increase profits.
Filling adhesive glue tube, because of the high requirements for sealing, usually in the choice of closed mouth flat mouth of the cylindrical aluminum tube, but also choose to match the regular cap with a spike.
And instant glue because of its glue fast drying, so in addition to the choice of the smaller mouth of the aluminum tube, but also with a two-section spiked cover, in order to achieve the requirements of sealing, quality assurance; but if you purchase the aluminum tube for the opening cylindrical, you need to match the sealant cover, the consumer in the open use, but also to a certain extent to prevent the filling of leakage, curing.
But this is only a general rule, because of the choice of packaging aluminum tube with cover, but also to consider the characteristics of the contents, product packaging design, size requirements, and the overall harmony and aesthetics. Using the same aluminum tube, with different matching caps, presenting different visual effects, the overall value of the aluminum tube will also be different!
Now, we are know how important to use the right lids for the products!
