Foil bags need to accumulate this knowledge from time to time, in everyday life. From time to time, get knowledge that work more efficiently, work better, and work faster. Some knowledge may be conscious or unconscious, then how can I let more friends know about this knowledge? Today I will analyze the tips of the bag closure. The material used was aluminum foil material. Recently, a customer purchased a batch of anti-static shielding bags. Then there is a zipper, here I define it as a zippered three-side anti-static foil bag. The customer is also very satisfied, after the bag is shipped to the customer. However, there was a problem when I sealed it. It was very ugly to seal up and I didn’t know how to deal with it. How to seal the vacuum bag? The seal of the most common food packaging bag is heat sealed. This is the need for a heating rod (sometimes heated in the form of a pulse), the force of the heating rod to bite, the time the heating rod is engaged, and I have said the problem of the sealing of the bag. Under the action of three factors, the heat sealable material inside the bag mouth is melted and then bonded. This form of heat sealing is generally better sealed. It may result in poor sealing. When sealing, I need to pay attention to the sealing, aesthetics and sealing material. When I heat seal, I don't know the temperature and some details. In that case, the product can't be guaranteed, causing great trouble to the customer. In particular, foods require a very good seal. Then the seal is also very beautiful. The customer often adjusts his heat sealer later. To be exact, aluminum foil bags and vacuum bags are essential for families. They can be used for sealed food packaging.

LED Strip 2835
15 lights, 30 lights, and 60 lights refer to the number of LED components welded per meter length of the LED strip. Generally speaking, the 1210 specification strip has 60 LEDs per meter, and the 5050 specification strip has 30 LEDs per meter. Special There are 60 LEDs per meter. The price of LED strips with different LED quantities is different, which is also an important factor in distinguishing the price of LED strips.
Color temperature
It refers to heating a standard black body. When the temperature rises to a certain level, the color starts to change from dark red-light red-orange-white-blue. When the color of a certain light source is the same as that of the black body, we call the absolute temperature of the black body at that time Is the color temperature of the light source.
Generally speaking, color temperature is not used as an indicator for evaluating LED strips, but many foreign customers will make a special requirement due to the use environment.
The color temperature of the light source is different, and the light color is also different:
The color temperature is below 3300K, and the light color is reddish to give a warm feeling; it has a stable atmosphere and a warm feeling. It is commonly known as warm color temperature.
The color temperature is in the middle of 3000-6000K, and people have no obvious visual psychological effect under this color, and there is a refreshing feeling; therefore, it is called "neutral" color temperature
The color temperature exceeds 6000K, and the light color is bluish, giving people a cool feeling, commonly known as cool color temperature.
