Three sides aluminum foil zipper bag adapt to the high standard requirements of various industries and is one of the most popular bag types.It with good barrier, preservation and sealing, suitable for the packaging of a variety of products. It has the following characteristics and advantages:
(1) Good mechanical properties: because the three-side sealing design melts the three sides together to forming a relatively stable structure, so that the aluminum foil bag can withstand greater internal pressure. This is very important for the packaging products that need to bear a certain pressure.
(2) Space saving and cost efficiency: compared with hard packaging, such as cans or glass bottles, the three-sided sealed aluminum foil bag occupies very little space before filling, which is conducive to transportation and storage, and can also significantly reduce the cost of packaging materials.
(3) Easy for processing and production: the three-side sealing design also has certain advantages in the processing and production process. Since only the three sides need to be thermosealed, the processing speed is faster and the production efficiency is higher than the unilateral or bilateral sealing.
(4) Wide range of applications: three-side sealed aluminum foil bags are very suitable for packaged food (such as snacks, coffee, tea), drugs, cosmetics, chemicals and other products that need good protection, so that they can meet the packaging needs of multiple industries.
(5) Environmental protection: compared with some other packaging materials, aluminum foil is easy to recycle and reuse, which helps to reduce the environmental burden.
