Paraffin Lab Sealing Film for Petri Dishes, 4 in x 125 ft, Grafting Tape
12 sold in last 24 hours
- WIDE FORMAT FOR FREQUENT USE ▶ The 4 in (10 cm) width provides broader coverage for larger laboratory openings, while the 125 ft (38 m) long roll supports frequent sealing with fewer roll changes.
- SELF-SEALING & 3–5× STRETCH ▶ Flexible film stretches 3–5× to conform around petri dishes, bottles, beakers, flasks, and irregular labware, then self-seals for controlled wrapping without separate sealing tape.
- FOR LARGER LAB OPENINGS ▶ The 4 in width is suited to wide-mouth bottles, beakers, flasks, larger laboratory containers, and other wider openings; the film can also be used for plant grafting and stem wrapping.
- -80°C TO 40°C CHEMICAL & UV RESISTANT ▶ Designed for laboratory use across the stated temperature range, with chemical and UV resistance; the film forms a waterproof surface barrier while remaining gas-permeable.
- RESPONSIVE AFTER-SALES SUPPORT ▶ Questions about product use, specifications, or your order? Our support team is available to assist from purchase through use, with responses within 24 hours.

Why is BM-PSF-992 widely recommended for lab use?
Based on field tests and user feedback from exhibitions and research labs, the BM-PSF-992 (3 cm × 15 m) is favored for its pre-cut design, ideal width for sealing, and time-saving performance in typical lab workflows.
How does Magic Phoenix sealing film perform better than competitors under similar temperature conditions?
Though both films share a 0–40°C usage range, Magic Phoenix shows better adaptability at critical temps due to refined manufacturing. It maintains stretchability and recovers performance after 65°C baking, unlike others prone to break or deform.
What makes Magic Phoenix more efficient and stretchable than other sealing films?
With a 125 μm thickness and 3–5× stretch ratio, Magic Phoenix achieves better flexibility than 127 μm competitor films. Thanks to improved processing, it stretches further with less material, making it more efficient and easier to apply.
How does Magic Phoenix perform in bacterial culture compared to similar sealing films?
In a 3-group E. coli OD600 test over 4.5 hours, Magic Phoenix achieved values of 1.55, 1.47, and 1.47 after 7× dilution—slightly higher than competitor films (1.55, 1.42, 1.47), indicating more consistent growth and reliable sealing support.
What makes Magic Phoenix sealing film more reliable for plant grafting applications?
After 168 hours of UV exposure, Magic Phoenix film remained intact with no cracking, ensuring consistent sealing. In contrast, stretched competitor films tend to degrade under prolonged UV, increasing the risk of failure in grafting tasks.
