At the beginning of plastic bottle planning, it is necessary for planners to
conduct market surveys, clarify customer needs, learn the strengths of similar
products in the same industry, understand the company's molding equipment and
production technology level, and establish the starting concept of the planned
products. It is necessary for the plastic bottle to have the function of
maintaining the contents. The plastic bottle can prevent moisture, water, dust,
and corrosion, and isolate the outside from dust, water, and other liquid
substances; avoid the pollution and corrosion of the packaging; avoid
ultraviolet rays Penetrate, get used to changes in ambient temperature, and
maintain packaging from sun and ultraviolet rays. The plastic bottle must have
the function of accepting the effect of external force. It can get used to a
variety of delivery methods and storage methods in the warehouse to maintain the
contents from being damaged.
Plastic bottles should have satisfactory stiffness and beautiful shape. The
most common shapes of plastic bottles are round, square, oval, etc. From the
perspective of application, they have their own advantages and disadvantages.
Round plastic bottles have high stiffness, but the appearance is not beautiful.
Square plastic bottles have beautiful appearance, but it is not easy to control
the uniform thickness of the plastic bottle during molding. Oval plastic bottles
have higher stiffness, but the manufacturing cost of the mold is higher.
Therefore, in order to ensure the stiffness of the plastic bottle, in addition
to selecting high stiffness data, the shape of the plastic bottle has to be
planned to enhance the stiffness and resistance of the plastic bottle Load
intensity.
Plastic bottles enable products to exhibit functions. Plastic bottles can go
through beautiful appearance, gorgeous colors, bright appearance and
transparency to show the product's display function, attract customers, and
arouse customers' purchase desire. Plastic bottles should have a convenient
function. The opening of the plastic bottle should be opened and closed, and it
can be opened and closed repeatedly. The dumping of the contents should be
convenient, and the appearance of splashing can not occur.
To reduce packaging breakage and shipping weight, and to meet consumer safety
needs, today, many large retailers require beverage and food manufacturers to
use plastic packaging. From all aspects, while changing the packaging materials,
maintaining brand integrity and ensuring product quality are major challenges.
Because, changing a kind of glass packaging that has been accepted by the market
for a long time and has a high degree of recognition, consumers understand and
trust it into a plastic packaging, it is possible to cause a brand crisis in the
consumer market. In addition, many products requiring high-temperature
processing, such as sterilizers and hot-fill packaging, face technical
difficulties in this conversion trend.
A composite sealing cap-that is, a two-piece bottle cap, including a central
metal plate and a plastic outer ring-can help the brand to smoothly convert 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 sealing cover can bring a brand new image to the brand
through a reasonable combination of materials. Mineral water cap, juice bottle cap
and other
beverage cap can be made by automatic cap compression molding machine.
