plastic bag for packaging seafood
Sealing & Handle:
The basic requirements of frozen food packaging: from production, transportation to sales, maintain the quality characteristics of its products, prevent bacterial contamination and make it convenient to eat.For this purpose, packaging materials must have certain mechanical strength (high and low temperature resistance);Having resistance (high resistance to gas and liquid);Tolerance to content (acid and oil);Health;Operational resistance.
Packaging of frozen foods:
Currently, there are two types of packaging for frozen foods: soft and hard.Soft type is based on plastic film.Thick and hard packaging, such as slightly thicker paper packaging boxes, and composite aluminum foil stamping containers, the former occupies a large proportion.Currently, the common frozen food packaging in the market mostly adopts the following structure:
The product performance of 0PP /LLDPE structure can meet the requirements of moisture-proof, cold-resistant, and low-temperature heat-seal tensile strength, and the cost is relatively economical.
The packaging performance of NY/LLDPE structure can withstand freezing, impact and puncture, with relatively high cost and good packaging performance.
Structures such as PET/LDPE, PET/NY/LDPE and PET/VMPET/LDPE are also used in frozen products, but their utilization rate is relatively low.
There is also a simple P bag, such as vegetable packaging.The above product structure is the domestic market cryopreservation product package more concentrated structure.
