UV Photochromic Printing: a new printing option for bags UV photochromic printing is a special printing method which applies Sunlight or UV (ultraviolet) light properties to realize color change effect of printed matters.   Principle of Photochromic Color Change Ultraviolet light is invisible light in the violet range of the spectrum in the electromagnetic spectrum. The key point of UV photochromic printing is the application of special photochromic inks. Such inks include photochromic materials which have chemical reaction capabilities. Under the effect of the ultraviolet ray, the molecular structure of the photochromic matter in the ink varies so that a color change is achieved.   After printing photochromic ink, it needs to be coated with UV after printing, but the printing process is the same as that of ordinary ink. During the curing process, the ultraviolet light emitted by the UV lamp activates the photochromic substances in the ink, priming them for a color change. Once the printed material is later exposed to natural sunlight or a specific ultraviolet light source, the color-changing effect appears.    Because of photochromic color principle (the rate of discoloration will also change depending on the environment that the product is used.) Factors including light, application environment etc. may have a direct effect on life span depending on the product being used.   Application environment: Photochromic substances are easily oxidized by oxygen in the air. The photochromic material which has resistivity to the oxidation is effective to maintain the performance for a long time. Special processed or antioxidative type of photochromic ink has longer life than a regular ink. The life of the photochromic content is also influenced by temperature and humidity. Chemical reactions are accelerated by high temperatures and high humidity that cause the colouring of the photochromic materials to age. For example, the duration of stability of the photochromic materials may be shorter in humid tropical zones as compred to dry moderate zones.   Light Intensity: High intensity of ultraviolet light, the photochromic chemicals reaction speed is faster, the chemical process will more quickly, and aging of photochromic lens. For instance, when exposed to the natural sunlight, sometimes the service life of photochromic materials is very short. Their life span is relatively long since they are in the indoor environment with lower light intensity.   Usage Frequency: Usage frequency is the frequency with which the photochromic materials are actuated (ie, exposed to the ultraviolet or particular light source) in a given period of time. The photochromic materials are gradually damaged by the exposure of UV. Any single exposure results in some tiny alteration in molecular structure, and these miniscule changes add up over time and can be observed as deterioration in performance. The service life of photochromatic materials is extremely short at high frequency of use. One example of this is that a product which is used ten times per day with UV exposure, may have a photochromic life of a few months, while a product used once a day may last 1-2 years.   When this special principle of photosensitive color change is applied to photochromic printing technology, the application prospect is very broad. More directly, it introduces a new visual experience and surprises to bags, fashion and creativity and brings new visual effects to the product. For instance, patterns printed with UV photochromic inks on T-shirts, tote bags, backpacks, phone cases and other items can change their color under sunlight, which makes the product more fun and attractive. It is to be noted that the color switch effect is adjustable and difficult to be replicated by others, so it is very reliable to product anti-counterfeiting. As long as it continues to develop technologically, and becomes cheaper to use, it is just going to spread into more areas.   Special note at the end, it should be noted that this printing process has to be done in particular conditions e.g. not to be disturbed by natural light etc. Proper drying temperature and drying time can avoid damages of the photochromic substances during printing, which contributes to the effect of color change to be precise and stable. Similar premature aging of the photochromic substances can occur when the drying condition is such that the drying temperature is unduly high or the drying time is unduly long.     Author

One buzz, and the entire world presses against your face. On the subway, at the dinner table, even at 3 a.m. in bed, that pale screen-light acts like an invisible umbilical cord, tethering us to the cloud. Every absent-minded swipe quietly uploads your coordinates; every “Allow Location” can turn today’s footsteps into tomorrow’s data map, sold to strangers. The awkward truth? Most countries still haven’t written the rules. So we’re left with a private, almost absurd choice: step into a signal-proof cage or stay naked in the open—security or convenience, rarely both.     For 32 years we’ve done one thing: make bags that simply work better. From the very first stitch, “easy to use” has been our non-negotiable. Today we’re adding a fresh layer to that ease—security. Signals flit around inside a bag; we make sure they never make it out. Below, we break it down step by step: how a wafer-thin shielding fabric slips unnoticed into wallets, backpacks, briefcases, even an ordinary grocery tote, turning every pocket into a dead zone where phones go silent and privacy stays put.   Back then, cutting off radio waves meant wheeling in the hulking metal cages locked away in military bunkers. Now it only takes a strip of cloth. We took the RF shielding once sealed inside spacecraft and operating theaters and wove it straight into the fibers: a whisper-thin copper-ion mist wraps every yarn, while silver filaments thread through at micron-level precision. What rolls off the loom is a supple “soft armor” you can fold, cut, even toss in the wash. Stitch it into a pocket and you’ve got a pocket-sized Faraday cage: the moment a phone slips inside, it goes mute; prying signals bounce off like they’ve hit a wall. One zip, and the digital world falls silent.   Think of signal-blocking fabric as an “invisible lock.” It can be stitched into almost any bag, sealing out RFID skimmers, GPS trackers, and Bluetooth sniffers in one move. More than a data firewall, it’s a Do-Not-Disturb sign you can carry. Drop your phone, earbuds, or smartwatch into the shielded pocket and Wi-Fi and cellular vanish instantly—meetings, reading sessions, or playtime with the kids go uninterrupted. On the road, tuck your camera and spare phone into the shielded compartment of your carry-on: no leaks, just a few blissfully offline hours to watch the scenery instead of the screen. The same goes for wallets and passport sleeves—snap the shield shut before security, and both your data and your mind stay quiet.   Here’s the complete run-down of signal-blocking fabric in everyday bags： 1. Wallet & Passport SleeveSlip a 0.2 mm shielding layer between the billfold and card slots. Card readers can’t see your chips; slide your passport in the same pocket and no one can skim it while you queue at immigration.   2. Handbag / ToteAdd a removable “signal cocoon” in the main compartment. Drop the phone in—airplane mode without toggling a switch. Pull it out and bars pop back up instantly.   3. BackpackLine the laptop sleeve on all four sides. A 15.6" notebook disappears from Wi-Fi and Bluetooth the moment the zipper closes.   4. Travel Bag / Carry-on Sew a shielded stash pocket under the top lid for passport, backup phone, and camera cards. Even the airport “sniffer dogs” of RF leave empty-handed.   5. Briefcase / Document CaseKeep the outer face premium leather or Oxford cloth; back it with a full sheet of shielding fabric. Contracts, USB drives, and encrypted dongles sit in a silent vault no matter who’s running a spectrum recorder in the conference room.   6. Gym DuffelTuck an 18 × 10 cm “watch hut” above the shoe tunnel. Drop your smartwatch and earbuds in before you hit the treadmill—notifications stay outside the squat rack.   7. Student Backpack / Pencil PouchTurn the classic roll-top pencil case into a signal roll-cage. Phone goes in, fabric rolls shut, and the ringer never rings during first period.   8. Medical & Scientific Transit BagsUse heavy-duty metal-fiber cloth rated ≥90 dB to create soft Faraday crates of any size. Portable ultrasound probes or RFID-tagged blood samples travel in total radio silence, immune to data bleed or malicious pings.   A piece of fabric that looks utterly ordinary is quietly stitching military-grade EMI shielding into everyday life. Wallets, passport sleeves, 32-inch spinner cases—even the tiny schoolbag on a child’s back or a robot pack loaded with AI modules—are no longer just containers, they’re pocket-sized quiet zones. We’re not out to kill signals; we just want them to appear only where they’re supposed to. Safety and convenience, finally in the same stitch. To ODM/OEM partners and independent designers: let’s cut this fabric into new stories together, and bring the smart-security bag to everyone.   Author
