development history The commodity nature of packaging itself is becoming increasingly prominent, and it has become a special product that is no longer dependent on commodity production. It is a widely used product that all commodities cannot do without. Chinese scientists have developed an environmentally friendly plastic bag made of electrolytes, which can not only be decomposed harmlessly, but also dissolve in water. According to scientists, products made from common polymer plastic materials in daily life take hundreds of years to fully decompose and will exist on Earth for several hundred years. This new environmentally friendly plastic bag does not release harmful substances during the decomposition process, and can even decompose into natural substances that insects love, which greatly helps protect the natural environment. According to the production process, it is often divided into plastic packaging bags and composite packaging bags. Classified by production materials: high-pressure polyethylene plastic bags, low-pressure polyethylene plastic bags, polypropylene plastic bags, polyvinyl chloride plastic bags, 등. Classified by appearance: vest bag, straight tube bag, three-dimensional bag, square bottom bag. Sealed pockets, rubber strip bags, shaped bags, 등. Plastic packaging bags include plastic woven bags and plastic film bags. The former has the characteristics of light weight, high strength, and corrosion resistance. After being lined with plastic film, it can prevent moisture and dampness; Light bags have a carrying capacity of less than 2.5kg, medium bags have a carrying capacity of 25-50kg, and heavy bags have a carrying capacity of 50-100kg. The latter’s lightweight bag has a carrying capacity of over 1kg; Medium bag carrying capacity 1-10kg; Heavy duty bag with a load capacity of 10-30kg; The load capacity of the container bag is over 1000kg. Plastic woven bag Plastic woven bags are mainly composed of polypropylene bags and polyethylene bags; According to the sewing method, it can be divided into sewn bottom bags and sewn edge bottom bags. Products obtained through warp and weft weaving are generally referred to as woven bags. Plastic film bag The raw material of plastic film bags is polyethylene. Plastic bags have indeed brought convenience to life, but this temporary convenience has brought long-term harm. Classified by production materials: high-pressure polyethylene plastic bags, low-pressure polyethylene plastic bags, polypropylene plastic bags, polyvinyl chloride plastic bags, 등. Classified by appearance: vest bag, straight tube bag, three-dimensional bag, square bottom bag. Sealed pockets, rubber strip bags, shaped bags, 등. Composite packaging bag Composite various materials with different characteristics together to improve the breathability, moisture permeability, oil resistance, water resistance, and chemical resistance of packaging materials, enabling them to exhibit insect resistance, dust resistance, microbial resistance, isolation from light, fragrance, odor, and other odors, as well as better mechanical strength and processing applicability for heat resistance, cold resistance, and impact resistance, and have good printing and decorative effects. Classified by packaging form: Three sided sealed, 음양 가방, 중간 밀봉, 베개 모양 가방, 오각형 밀봉 가방, 팔각형 밀봉 가방, 자립형 가방, 지퍼 가방, 빨대 가방, 롤 소재, 커버 소재, 기능별 분류 기타: 고차광 차폐 가방, 스팀 필름 가방, 정전기 방지 필름 가방, 항균 필름 가방, 김서림 방지 필름 가방, 진공 가방, 내화학 필름 가방, 탈산소 포장 필름 가방, 변경된 분위기 포장 필름 가방, 소재별 분류 기타: 레이저 코팅 알루미늄 필름 복합지 소재, 레이저 전사지 소재, 종이 복합 소재, 알루미늄 복합 소재, 플라스틱 복합 소재, 원단 복합 소재, 등. 포장 가방 제작용 복합 유연 포장 소재는 최종적으로 다양한 포장 가방으로 제작되어야 사용 가능. 가방을 만드는 방법에는 두 가지가 있다. One is that the packaging manufacturer uses roll film to fill and form various packaging bags on an automatic packaging machine; Another reason is that the bag making mechanism produces various packaging bags and then fills them with contents. Due to the precise control of professional bag making, beautiful bag shapes, large variations in bag making, and multiple bag shapes, in many cases, bags are first made. The main varieties of bags include: three sided sealed bags (palm sealed bags), back sealed bags, folded bags (organ bags), upright bags, 등.
