In-mold labeling process
In-mold labeling process is a new packaging technology, it will be pre-printed images on polymer materials, and then the printed image labels directly into the mold in the predefined molding area, in the process of product injection molding so that the label and the container fused together, the label and the product surface is flush with the appearance of the pattern as directly printed on the surface of the product in general. Compared with laser etching technology, in-mold labeling technology has the following advantages:
- High clarity, because there is no fuzzy edges produced by laser ablation, printing accuracy can easily reach more than 1200 dpi, which is more than 4 times the best level of laser etching technology.
- The contrast is obvious, and a near-ideal black and white contrast can be achieved during printing, with a contrast much higher than the gray-black or gray-white contrast produced by laser etching. The high definition and strong contrast ensure the reliability of bottom code reading.
- Colors can be achieved. While relying on laser etching can only achieve monochromatic contrast, the in-mold labeling process based on printing technology can introduce color. Different color combinations increase the information channels and allow more information to be encoded on a limited area without shrinking the encoded graphic points (color code or 3D code).
- Reducing the wall thickness of the product while ensuring the structural strength of the product, because the thickness of the label is extremely thin, the frozen storage tubes produced based on the in-mold labeling process can be regarded as a whole with a uniform wall thickness. It does not have the problem of doping additives to affect the biological activity or background of the sample in response to laser ablation, nor does it bring about the problems of wall thickness overrun and separation of the two-layer structure produced by two-color injection molding. The former affects the container’s responsiveness to temperature changes (e.g. programmed cooling or warming) while the latter affects the structural strength of the product under drastic temperature changes.
- Good firmness, in-mold labeling of the label surface will be covered with a protective layer made of polymer materials. This protective layer is sufficient to meet the needs of normal use of wear-resistant, in organic solvents, high-temperature steam sterilization, liquid nitrogen cryogenic freezing and ultrasonic cleaning and other extreme conditions can show good resistance.
Product Features
Great variety
BANN’s cryopreservation tubes range from 0.3 ml to nearly 30 ml, with internal and external caps and different internal diameters for the same volume. These tubes are designed to meet the diverse needs of sample preservation.
Reliable Quality
Our products are made from FDA approved food grade raw material particles to ensure that the raw materials do not contain harmful substances that affect test results or interfere with biological samples. All production, assembly, and packaging are done in a class 100,000 cleanroom using automated equipment, minimizing manual operations and interventions. To further avoid the contamination brought in by the production process
Uniform in Size
These products need to be adapted to automation equipment, so the dimensional accuracy and uniformity requirements are extremely high. BANN develops and produces batch cap opener synchronously and establishes close cooperation relationship with many automation equipment companies. Through the construction of perfect quality control system, the application of advanced automated testing equipment, and automated production system, to ensure that the dimensional accuracy and uniformity of the products to meet the requirements of automated equipment smooth coordination.
Reliable Reading
Produced using a patented in-mold labeling process, the graphic contrast and clarity on the pre-made digitally printed labels is higher than laser etching, the labels are located flat on the surface of the product, and the protective layer is matte-finished to ensure that the labels are read reliably.
Standardization
All tubes are designed to be held under the SBS format, with a stop-turn snap-lock structure at the bottom of the tubes, which works in conjunction with the pattern on the caps to meet the need for automated uncapping. Tubes of different volumes are optimized to achieve a close proximity in height, which allows the fixed freezer rack to accommodate different types of sample tubes to meet the requirements of access and storage of changing sample types.
Enriched coding
Based on high-precision printing technology, the tiny space at the bottom of the cryopreservation tube can be used to make 2D barcode graphic as well as corresponding clear code, which can still ensure the accurate access to information in the absence of specialized equipment for reading. In addition, the 1D barcode or corresponding clear code, or specific logo or mark can be made on the side wall, which is the same as the code on the bottom.
Comprehensive System
BANN not only provides consumables, but also provides batch decoders and cap openers associated with consumables, which have been verified through long-term and in-depth cooperation with BANN’s consumables. At the same time, the software provides standard interfaces for integration with other automation equipment or information systems.
